Description
Organisches elektronisches BauelementOrganic electronic component
Die Erfindung betrifft ein organisches elektronisches Bauelement, insbesondere eines mit einer aktiven Schicht aus im spannungsfreien Zustand nicht konjugiertem Material.The invention relates to an organic electronic component, in particular one with an active layer of material that is not conjugated in the stress-free state.
Bekannt sind aus der US 5,247,190 organische elektronische Bauelemente wie organische Leuchtdioden (OLED) , die eine semitransparente untere Elektrode, eine organische aktive Schicht, im wesentlichen bestehend aus einem konjugierten po- lymeren Film und eine obere Elektrode umfassen. Ein konjugiertes Material ist definiert durch eine durchgehende Kette von durch π-Konj gation, also im Wesentlichen auf gleicher energetischer Höhe liegender besetzter π-Orbitale, verbunde- nen Molekülen und/oder Molekülteile. Als konjugierte Polymere bezeichnet man Polymere mit einem delokalisierten π-Elektro- nensystem entlang der polymeren Hauptkette. Das delokalisierte π-Elektronensystem verleiht dem Polymer halbleitende Eigenschaften, weil es ihm die Möglichkeit gibt positive und negative Ladungsträger mit hoher Beweglichkeit entlang der polymeren Hauptkette zu unterstützen. Diese Art der Polymeren wird unter anderem in der US 5,247,190 beschrieben.From US 5,247,190 organic electronic components such as organic light-emitting diodes (OLED) are known which comprise a semi-transparent lower electrode, an organic active layer, essentially consisting of a conjugated polymer film and an upper electrode. A conjugated material is defined by a continuous chain of π orbitals, connected molecules and / or molecular parts occupied by π conjugation, that is to say essentially at the same energy level. Conjugated polymers are polymers with a delocalized π-electron system along the main polymer chain. The delocalized π electron system gives the polymer semiconducting properties because it gives it the ability to support positive and negative charge carriers with high mobility along the polymer main chain. This type of polymer is described, inter alia, in US Pat. No. 5,247,190.
Aus der DE 103 207 13.9 und der DE 10 2004 001 865.0 sind Co- polyarylborane als Material für organisch aktive Schichten für OLEDs bekannt.DE 103 207 13.9 and DE 10 2004 001 865.0 have disclosed copolyarylboranes as a material for organically active layers for OLEDs.
Die bekannten polymeren konjugierten Verbindungen sind nicht so stabil gegen die während des Betriebs ablaufenden Oxidati- ons- und Reduktionsprozesse, dass sehr langlebige Produkte mit ihnen herstellbar sind.The known polymeric conjugated compounds are not so stable against the oxidation and reduction processes that take place during operation that very long-lived products can be produced with them.
Aufgabe der Erfindung ist es, ein Material für eine aktive Schicht eines organischen elektronischen Bauelements zu schaffen, das sich im Ruhezustand wie ein nicht konjugiertes Material und im Betrieb wie ein. onjugiertes polymeres Material verhält, aber das gegenüber Oxidations- und/oder Reduk-
tionsprozessen nicht so instabil ist, wie die für diese Anwendung bekannten konjugierten Verbindungen.The object of the invention is to provide a material for an active layer of an organic electronic component, which is in the idle state as a non-conjugated material and in operation as a. conjugated polymeric material behaves, but that against oxidation and / or Reduk- tion processes is not as unstable as the conjugated compounds known for this application.
Gegenstand der Erfindung ist ein organisches elektronisches Bauelement wie eine OLED mit einer unteren, eventuell semitransparenten Elektrode, zumindest einer organischen aktiven Schicht und einer oberen Elektrode, wobei die zumindest eine organische aktive Schicht ein im spannungslosen Zustand nicht-konjugiertes organisches Material umfasst.The invention relates to an organic electronic component such as an OLED with a lower, possibly semi-transparent electrode, at least one organic active layer and an upper electrode, the at least one organic active layer comprising an organic material that is non-conjugated in the de-energized state.
Die organische aktive Schicht kann entweder eine organische halbleitende Schicht und/oder eine organische Lichtemittierende Schicht sein. Als organisches Material wird hier jede Art von Material bezeichnet mit Ausnahme der traditionellen anorganischen Halbleitermaterialien, also Silizium, Gallium-Arsenid und/oder Mischungen davon enthaltenden Materialien. Die organische aktive Schicht kann dabei das nicht- konjugierte Polymer nur zu einem gewissen Prozentsatz enthal- ten und im Wesentlichen sogar aus einem konjugierten polymeren organischen Material geschaffen sein, solange das nicht- konjugierte polymere organische Material gemäß der Erfindung in der aktiven Schicht enthalten ist und während des Betriebs des Bauelements halbleitende und/oder Licht emittierende Ei- genschaften zeigt.The organic active layer can be either an organic semiconducting layer and / or an organic light-emitting layer. Any type of material is referred to here as organic material with the exception of the traditional inorganic semiconductor materials, that is to say silicon, gallium arsenide and / or mixtures thereof. The organic active layer can contain only a certain percentage of the non-conjugated polymer and can essentially even be made of a conjugated polymeric organic material, as long as the non-conjugated polymeric organic material according to the invention is contained in the active layer and shows semiconducting and / or light-emitting properties during the operation of the component.
Das nicht-konjugierte organische Material ist beispielsweise ein polymeres Material mit Wiederholeinheiten, wobei jede Wiederholeinheit eine Struktur hat, die wegen fehlender be- setzter π-Orbitale keine durch konjugierte Kette hat. Beispielsweise handelt es sich um eine Lewis-Säure mit konjugierten Ketten organischer Moleküle als Liganden. Nach Anlegen elektrischer Spannung an das Molekül oder Polymer kann sich jedoch eine Konjugation, die dem Material halbleitende Eigenschaften verleiht, ergeben. Diese Verbindungen sind sowohl Elektronen angelverbindungen als auch nicht konjugierte Verbindungen sind und müssen mit Elektronen geladen werden,
bevor sie leitend werden, d.h. sich wie konjugierte Verbindungen verhaltend werden. Derartige Materialien sind entweder zumindest Bestandteile oder bilden das organische Material, das die aktiven Schichten des erfindungsgemäßen organischen elektronischen Bauelements bildet. Die damit hergestellten organischen aktiven Schichten sind gegenüber von Oxidations- oder Reduktionsprozessen stabiler als reine konjugierte poly- mere Verbindunge .The non-conjugated organic material is, for example, a polymeric material with repeating units, each repeating unit having a structure which, owing to the lack of occupied π orbitals, has no conjugated chain. For example, it is a Lewis acid with conjugated chains of organic molecules as ligands. However, after electrical voltage is applied to the molecule or polymer, a conjugation can result which gives the material semiconducting properties. These compounds are both electron fishing compounds and are non-conjugated compounds and must be charged with electrons, before they become conductive, ie behave like conjugated connections. Such materials are either at least components or form the organic material which forms the active layers of the organic electronic component according to the invention. The organic active layers produced with them are more stable to oxidation or reduction processes than pure conjugated polymeric compounds.

Leuchtdioden (OLEDs) , organischen photovoltaischen Bauelementen, z.B. Solarzellen, or- ganischen Transistoren und/oder Detektoren gebraucht werden. Nachteilig an den konjugierten organischen Polymeren ist jedoch, dass sie nicht sehr stabil gegenüber den während des Betriebs des organischen Halbleiters ablaufenden Oxidations- und Reduktionsreaktionen sind, so dass mit den herkömmlichen konjugierten polymeren Materialien keine elektronischen Bauelemente von hoher Lebensdauer gefertigt werden konnten.So far, only conjugated polymers are known as semiconducting organic polymers, such as those used for the production of organic electronic components such as organic self-emitting components, e.g. Light emitting diodes (OLEDs), organic photovoltaic components, e.g. Solar cells, organic transistors and / or detectors are needed. A disadvantage of the conjugated organic polymers, however, is that they are not very stable to the oxidation and reduction reactions taking place during the operation of the organic semiconductor, so that it was not possible to produce long-life electronic components with the conventional conjugated polymeric materials.
