US08232549B2 Iridium complex containing carbazole-substituted pyridine and phenyl derivatives as main ligand and organic light-emitting diodes containing the same 有权
含有咔唑取代的吡啶和苯基衍生物作为主要配体的铱络合物和含有它们的有机发光二极管

Iridium complex containing carbazole-substituted pyridine and phenyl derivatives as main ligand and organic light-emitting diodes containing the same
Abstract:
The present invention relates to a novel iridium complex into which carbazole-substituted pyridine derivatives and various substituents-substituted phenyl derivatives are introduced as main ligand and a electrophosphorescence diode containing the same as a dopant of a light-emitting layer. When the iridium complex according to the present invention is applied to an organic light-emitting diode, the heat-resistance property and the light-emitting property can be significantly improved as well as the light-emitting efficiency and the like can be significantly improved by doping the iridium complex compound into the light-emitting layer as compared to the conventional organic light-emitting diode.
Abstract(Chinese):

本发明涉及引入咔唑取代的吡啶衍生物和各种取代基取代的苯基衍生物作为主要配体的新型铱络合物和包含与发光层的掺杂剂相同的电磷光二极管。 当将根据本发明的铱络合物应用于有机发光二极管时，可以显着提高耐热性和发光性，并且可以通过以下方式显着提高发光效率等： 与传统的有机发光二极管相比，将铱络合物掺杂到发光层中。
