DOTANDEN FÜR ORGANISHE HABLEITER DOTANDEN FOR ORGANISM HOLDITER
Beschreibungdescription
Die Erfindung betrifft einen Dotanden zur Dotierung eines organischen halbleitenden Matrixmaterials zur Veränderung der elektrischen Eigenschaften desselben, die Verwendung des Dotanden, ein dotiertes halbleitendes Matrixmaterial sowie ein aus diesem hergestelltes elektronisches Bauelement.The invention relates to a dopant for doping an organic semiconductive matrix material for changing the electrical properties thereof, the use of the dopant, a doped semiconductive matrix material and an electronic component made therefrom.
Schon seit einigen Jahrzehnten ist das Dotieren von Siliziumhalbleitern Stand der Technik. Danach wird durch Erzeugung von Ladungsträgern im Material eine Erhöhung der zunächst recht niedrigen Leitfähigkeit sowie je nach Art des verwendeten Dotanden eine Veränderung im Fermi-Niveau des Halbleiters erreicht.For some decades doping of silicon semiconductors has been state of the art. Thereafter, an increase in the initially low conductivity and, depending on the type of dopant used, a change in the Fermi level of the semiconductor is achieved by generating charge carriers in the material.
Seit einigen Jahren ist nun aber auch bekannt geworden, dass man organische Halbleiter ebenfalls durch Dotierung hinsichtlich ihrer elektrischen Leitfähigkeit stark beeinflussen kann. Solche organischen halbleitenden Matrixmaterialien können entweder aus Verbindungen mit guten Elektronendonator-Eigenschaften oder aus Verbindungen mit guten Elektronenalczeptor-Eigenschaften aufgebaut werden. Zum Dotieren von Elektronendonator- Materialien sind starke Elektronen-Akzeptoren wie Tetracyanochinondimethan (TCNQ) oder 2,3,5,6-Tetrafluoro-tetracyano-l,4-benzochinondimethan (F4TCNQ) bekannt geworden. M. Pfeiffer, A. Beyer, T. Fritz, K. Leo, Appl. Phys. Lett, 73 (22), 3202-3204 (1998). und J. Blochwitz, M. Pfeiffer, T. Fritz, K. Leo, Appl. Phys. Lett., 73 (6), 729-731 (1998). Diese erzeugen durch Elektronentransferprozesse in elektronendonatorartigen Basismaterialien (Löchertransportmaterialien) sog. Löcher, durch deren Anzahl und Beweglichkeit sich die Leitfähigkeit des Basismaterials mehr oder weniger signifikant verändert. Als Matrixmaterialien mit Löchertransporteigenschaften sind beispielsweise N,N'-perarylierte
Benzidine TPD oder N,N',N"-perarylierte Starburstverbindungen, wie die Substanz TDATA, oder aber auch bestimmte Metallphthalocyanine, wie insbesondere Zinkphthalocyanin ZnPc bekannt.For some years now it has become known that organic semiconductors can also be strongly influenced by doping with regard to their electrical conductivity. Such organic semiconducting matrix materials can be constructed from either compounds with good electron donating properties or from compounds having good electron accepting properties. For doping electron donating materials, strong electron acceptors such as tetracyanoquinonedimethane (TCNQ) or 2,3,5,6-tetrafluoro-tetracyano-1,4-benzoquinone dimethyne (F4TCNQ) have become known. M. Pfeiffer, A. Beyer, T. Fritz, K. Leo, Appl. Phys. Lett, 73 (22), 3202-3204 (1998). and J. Blochwitz, M. Pfeiffer, T. Fritz, K. Leo, Appl. Phys. Lett., 73 (6), 729-731 (1998). These generate by electron transfer processes in electron donor-like base materials (hole transport materials) so-called. Holes, the number and mobility of which changes the conductivity of the base material more or less significantly. Examples of matrix materials with hole transport properties are N, N'-perarylated Benzidine TPD or N, N ', N "-perarylated starburst compounds, such as the substance TDATA, or else certain metal phthalocyanines, in particular zinc phthalocyanine ZnPc known.
Die bisher untersuchten Verbindungen haben jedoch für eine technische Anwendung Nachteile in der Produktion dotierter halbleitender organischer Schichten oder von entsprechenden elektronischen Bauteilen mit derartigen dotierten Schichten, da die Fertigungsprozesse in großtechnischen Produktionsanlagen oder solchen im Technikumsmaßstab nicht immer ausreichend präzise gesteuert werden können, was zu hohem Steuerungs- und Regelaufwand innerhalb der Prozesse fuhrt, um eine gewünschte Produktqualität zu erzielen, oder zu unerwünschten Toleranzen der Produkte. Ferner bestehen Nachteile bei der Verwendung bisher bekannter organischer Donatoren bezüglich der elektronischen Bauelementstrukturen wie Leuchtdioden (OLEDs), Feldeffekttransistor (FET) oder Solarzellen selber, da die genannten Produktionsschwierigkeiten bei der Handhabung der Dotanden zu unerwünschten Ungleichmäßigkeiten in den elektronischen Bauteilen oder unerwünschten Alterungseffekten der elektronischen Bauteile führen können. Gleichzeitig ist jedoch zu beachten, dass die zu verwendenden Dotanden geeignete Elektronenaffinitäten und andere für den Anwendungsfall geeignete Eigenschaften aufweisen, da beispielsweise die Dotanden unter gegebenen Bedingungen auch die Leitfähigkeit oder andere elektrische Eigenschaften der organisch halbleitenden Schicht mit bestimmen.However, the compounds examined so far have disadvantages for the production of doped semiconducting organic layers or of corresponding electronic components with such doped layers, since the production processes in large-scale production plants or those on a pilot plant scale can not always be controlled sufficiently precisely, leading to high control and control effort within the processes leads to achieve a desired product quality, or undesirable tolerances of the products. Furthermore, there are disadvantages in the use of previously known organic donors with respect to the electronic component structures such as light-emitting diodes (OLEDs), field effect transistor (FET) or solar cells themselves, since the mentioned production difficulties in handling the dopants to unwanted irregularities in the electronic components or unwanted aging effects of the electronic components being able to lead. At the same time, however, it should be noted that the dopants to be used have suitable electron affinities and other properties suitable for the application, since, for example, the dopants also determine the conductivity or other electrical properties of the organic semiconductive layer under given conditions.
Der Erfindung liegt daher die Aufgabe zugrunde, organische Dotanden zur Dotierung organischer Halbleiter bereitzustellen, die im Produktionsprozess leichter handhabbar sind und die zu elektronischen Bauteilen führen, deren organische halbleitende Materialien reproduzierbarer herstellbar sind.The invention is therefore based on the object of providing organic dopants for doping organic semiconductors which are easier to handle in the production process and which lead to electronic components whose organic semiconducting materials can be produced in a reproducible manner.
Erfindungsgemäß wird diese Aufgabe durch einen Dotanden gemäß Anspruch 1 gelöst, wobei sich bevorzugte Ausführungsformen aus den Unteransprüchen ergeben.
Die erfmdungsgemäßen Dotanden zeigen überraschenderweise eine äußerst hohe Elektronenaffinität, thermische Stabilität, Sublimierbarkeit und Diffusionsbeständigkeit in Halbleiterschichten, wobei die Kombination dieser Eigenschaften nicht erwartet werden konnte.According to the invention, this object is achieved by a dopant according to claim 1, wherein preferred embodiments result from the subclaims. Surprisingly, the dopants according to the invention exhibit an extremely high electron affinity, thermal stability, sublimability and diffusion resistance in semiconductor layers, whereby the combination of these properties could not be expected.
Die Flüchtigkeit kann als die unter gleichen Bedingungen (beispielsweise einem Druck von 2 x 10"4 Pa und einer vorgegebenen Verdampfungstemperatur, beispielsweise 150°C) gemessene Verdampfungsrate oder als Bedampfungsrate eines Substrats gemessen als Schichtdickenwachstum je Zeiteinheit (nm/s) unter sonst gleichen Bedingungen bestimmt werden. Vorzugsweise beträgt die Flüchtigkeit der erfindungsgemäßen Verbindungen das < 0,95- oder 0,9-fache, besonders bevorzugt das < 0,8-fache, weiter bevorzugt das < 0,5-fache, besonders bevorzugt das < 0,1 -fache oder das < 0,05-fache oder < 0,01 -fache von F4TCNQ oder weniger.The volatility can be used as the under the same conditions (for example, a pressure of 2 x 10 "4 Pa and a predetermined evaporation temperature, for example 150 ° C) measured evaporation rate or rate of vapor deposition of a substrate measured as a layer thickness growth per unit time (nm / s) under otherwise identical conditions The volatility of the compounds according to the invention is preferably <0.95 or 0.9 times, particularly preferably <0.8 times, more preferably <0.5 times, particularly preferably <0.1 -fold or <0.05-fold or <0.01-fold of F4TCNQ or less.
Die Bedampfungsrate des Substrats mit den erfindungsgemäßen Verbindungen kann beispielsweise unter Verwendung eines Quartzdickenmonitors bestimmt wird, wie er beispielsweise bei der Herstellung von OLEDs üblicherweise eingesetzt wird. Insbesondere kann das Verhältnis der Bedarnpfungsraten von Matrixmaterialien und Dotanden durch unabhängige Messungen , derselben unter Verwendung von zwei getrennten Quartzdickenmonitoren gemessen werden, um das Dotierungsverhältnis einzustellen.The evaporation rate of the substrate with the compounds according to the invention can be determined, for example, using a quartz thickness monitor, as is commonly used, for example, in the production of OLEDs. In particular, the ratio of the occlusion rates of matrix materials and dopants can be measured by independent measurements using the same, using two separate quartz thickness monitors to adjust the doping ratio.
Die Flüchtigkeit relativ zu der von F4TCNQ kann sich jeweils auf die der reinen Verbindung oder auf die Flüchtigkeit aus einem gegebenen Matrixmaterial, beispielsweise ZnPc, beziehen.The volatility relative to that of F4TCNQ may refer respectively to that of the pure compound or to the volatility from a given matrix material, for example ZnPc.
Es versteht sich, dass die erfindungsgemäßen Verbindungen vorzugsweise derart beschaffen sind, dass sie mehr oder weniger oder praktisch unzersetzt verdampfen. Es können unter Umständen jedoch auch zielgerichtet Precursor als Dotandenquelle eingesetzt werden, die die erfindungsgemäß verwendeten Verbindungen freisetzen, beispielsweise Säureadditionssalze,
beispielsweise einer flüchtigen oder nichtflüchtigen anorganischen oder organischen Säure, oder Charge-Transfer-Komplexe derselben, wobei die Säuren bzw. Elektronen-Donatoren vorzugsweise nicht oder nur gering flüchtig sind oder der Charge-Transfer-Komplex selber als Dotand wirkt.It is understood that the compounds of the invention are preferably such that they evaporate more or less or virtually undecomposed. However, under certain circumstances, it is also possible to use precursors as dopant source in a targeted manner which release the compounds used according to the invention, for example acid addition salts. for example, a volatile or nonvolatile inorganic or organic acid, or charge-transfer complexes thereof, wherein the acids or electron donors are preferably not or only slightly volatile or the charge-transfer complex itself acts as a dopant.
Vorzugsweise ist der Dotand derart ausgewählt, dass er unter sonst gleichen Bedingungen wie insbesondere Dotierungskonzentration (Molverhältnis Dotand:Matrix, Schichtdicke, Stromstärke) bei gegebenem Matrixmaterial (beispielsweise Zinkphtalocyanin oder einem anderen weiter unten genannten Matrixmaterial) eine genau so hohe oder vorzugsweise eine höhere Leitfähigkeit erzeugt als F4TCNQ, beispielsweise eine Leitfähigkeit (S/cm) von größer/gleich dem 1,1 -fachen, 1,2-fachen oder größer/gleich dem 1,5 -fachen oder zweifachen derjenigen von F4TCNQ als Dotand.Preferably, the dopant is selected such that under otherwise identical conditions such as in particular doping concentration (molar ratio of dopant: matrix, layer thickness, current strength) for a given matrix material (for example, zinc phthalocyanine or another matrix material mentioned below) generates a precisely as high or preferably a higher conductivity as F4TCNQ, for example, a conductivity (S / cm) of greater than or equal to 1.1 times, 1.2 times or greater / equal to 1.5 times or twice that of F4TCNQ as dopant.
Vorzugsweise ist der erfindungsgemäß verwendete Dotand derart ausgewählt, dass das mit diesem dotierte halbleitende organische Matrixmaterial nach einer Temperaturänderung von 100°C auf Raumtemperatur (20°C) noch > 20%, vorzugsweise > 30%, besonders bevorzugt > 50% oder 60% der Leitfähigkeit (S/cm) des Wertes bei 100°C aufweist.Preferably, the dopant used in the invention is selected such that the doped with this semiconducting organic matrix material after a temperature change of 100 ° C to room temperature (20 ° C) still> 20%, preferably> 30%, more preferably> 50% or 60% of Conductivity (S / cm) of the value at 100 ° C.
Die erfindungsgemäßen Dotanden weisen eine hohe Verdampfungstemperatur bzw. eine geringe Flüchtigkeit auf, so daß Produktionsprozesse zum Dotieren von organischen halbleitenden Materialien besser kontrolliert und damit mit geringem Aufwand und reproduzierbar durchgeführt werden können. Die Chinonderivat- Verbindungen, die gemäß der vorliegenden Erfindung als Dotanden vorgeschlagen werden, ermöglichen eine ausreichende elektrische Leitfähigkeit der organischen halbleitenden Matrix bei günstiger Elektronenaffinität der Dotanden, wobei gleichzeitig in den jeweiligen Bauteilen geringe Diffusionskoeffizienten, die zeitlich gleichbleibende Bauelementstrukturen gewährleisten, bereitgestellt werden. Ferner kann durch die erfindungsgemäßen Dotanden die Ladungsträgerinjektion von Kontakten in die dotierte Schicht verbessert werden. Ferner kann das dotierte organische Halleitermaterial bzw. das resultierende elektronische Bauteil
aufgrund der erfindungsgemäß verwendeten Verbindungen eine verbesserte Langzeitstabilität aufweisen. Dies betrifft beispielsweise eine Verringerung der Dotandenkonzentration mit der Zeit. Ferner betrifft dies die Stabilität der dotierten Schicht, die benachbart zu undotierten Schichten eines elektrooptischen Bauteils angeordnet ist, so daß elelctrooptische Bauteile mit erhöhter Langzeitstabilität der elektrooptischen Eigenschaften die Lichtausbeute bei einer vorgegebenen Wellenlänge, Wirksamkeit einer Solarzelle oder dergleichen präsentieren.The dopants according to the invention have a high vaporization temperature or a low volatility, so that production processes for doping organic semiconducting materials can be better controlled and thus can be carried out with little effort and reproducibly. The quinone derivative compounds which are proposed as dopants according to the present invention allow sufficient electrical conductivity of the organic semiconducting matrix with favorable electron affinity of the dopants, while at the same time providing low diffusion coefficients in the respective components which ensure component structures which are identical over time. Furthermore, the charge carrier injection of contacts into the doped layer can be improved by the dopants according to the invention. Furthermore, the doped organic semiconductor material or the resulting electronic component have improved long-term stability due to the compounds used in the invention. This concerns, for example, a reduction of the dopant concentration with time. Further, this relates to the stability of the doped layer disposed adjacent to undoped layers of an electro-optical device so that electro-optical devices having increased long-term stability of the electro-optical characteristics present the light output at a given wavelength, efficiency of a solar cell or the like.

a) Mischverdampfung im Vakuum mit einer Quelle für HT und einer für den Dotand.a) Mixed evaporation in vacuo with a source of HT and one for the dopant.
b) Sequentielles Deponieren von HT und Dotand mit anschliessender Eindiffusion des Dotanden durch thermische Behandlungb) Sequential deposition of HT and dopant with subsequent diffusion of the dopant by thermal treatment

d) Oberflächendotierung einer HT-Schicht durch eine oberflächlich aufgebrachte Schicht von Dotandend) Surface doping of an HT layer by a superficially applied layer of dopants
Die Dotierung kann derart erfolgen, dass der Dotand aus einer Precursor- Verbindung heraus verdampft wird, die beim Erhitzen und/oder Bestrahlung den Dotanden freisetzt. Die
Bestrahlung kann mittels elektromagnetischer Strahlung, insbesondere sichtbarem Licht, UV- Licht oder IR-Licht erfolgen, beispielsweise jeweils Laserlicht, oder auch durch andere Strahlungsarten. Durch die Bestrahlung kann im wesentlichen die zur Verdampfung notwendige Wärme bereitgestellt werden, es kann auch gezielt in bestimmte Banden der zu verdampfenden Verbindungen bzw. Precursor oder Verbindungskomplexe wie Charge- Transfer-Komplexe eingestrahlt werden, um beispielsweise durch Überführung in angeregte Zustände die Verdampfung der Verbindungen durch Dissoziation der Komplexe zu erleichtern. Es versteht sich, dass die nachfolgend beschriebenen Verdampfungsbedingungen sich auf solche ohne Bestrahlung richten und für Vergleichszwecke einheitliche Verdampfungsbedingungen heranzuziehen sind.The doping can be carried out in such a way that the dopant is evaporated out of a precursor compound which releases the dopant on heating and / or irradiation. The Irradiation can be carried out by means of electromagnetic radiation, in particular visible light, UV light or IR light, for example, in each case laser light, or else by other types of radiation. The irradiation can essentially provide the heat necessary for the evaporation, it can also be irradiated deliberately into specific bands of the compounds to be vaporized or precursors or compound complexes such as charge-transfer complexes in order, for example, to convert the compounds into excited states to facilitate by dissociation of the complexes. It is understood that the evaporation conditions described below are directed to those without irradiation and for comparison purposes uniform evaporation conditions are used.
