| Abstract [eng] |
Solution processable bipolar materials have been reported as emitters and host materials in organic light emitting diodes (OLEDs) [1]. These materials exhibited a thermally activated delayed fluorescence nature and have the capability of harvesting triplet excitons from excited triplet to singlet states by reverse intersystem crossing [2]. Thus, the TADF materials based organic LEDs have reached an internal quantum efficiency of nearly 100%. Herein, we have successfully designed and synthesized solution-processable bipolar carbazolebenzophenone derivatives as host materials, i.e. 4,4’-di(3-phenylcarbazol-9-yl)benzophenone (BPBCzO) and 4,4’-di[3-[4-(carbazol-9-yl)phenyl] carbazol-9-y] benzophenone (BCzBCzO). Structures of objective materials are shown in Figure 1. [...]. |
