摘要：

基于四苯基乙烯衍生物设计合成了两种蓝光材料TPE-4Br和TPE-3Br，并将其作为有机发光二极管（OLED）器件的发光层，研究发现其可与合适的邻层（空穴传输层/电子传输层）形成电致激基复合物。利用材料的本征激子发光及其电致激基复合物发光，可以得到理想的白光电致发光。将TPE-4Br和TPE-3Br掺杂于mCP中作为发光层，以TAPC和TmPyPB分别作为空穴传输层和电子传输层分别制备器件A和器件B，所得器件在操作电压为9 V时的色坐标分别为（0.32，0.33）和（0.31，0.34）。其中器件B的最大亮度和最大电流效率分别为364.66 cd·m-2与0.79 cd·A-1。

Abstract:

Two new blue-light-emitting materials based on tetraphenylethylene (TPE), TPE-4Br, and TPE-3Br have been designed and synthesized. They have been used as emitting materials in organic light-emitting diodes (OLEDs) and have been found to form electroplex with an appropriate neighboring hole or electron transporting layer. Using the intrinsic local exciton emission and electroplex emission, desirable white electroluminescence has been obtained. Using TPE-4Br and TPE-3Br in 1, 3-di (9H-carbazol-9-yl) benzene (mCP) matrix as the emitting layer, 4, 4'-(cyclohexane-1, 1-diyl) bis (N, N-di-p-tolylaniline) (TAPC) and 3, 3'-(5'-(3-(pyridin-3-yl) phenyl)-[1, 1':3', 1"-terphenyl]-3, 3"-diyl) dipyridine (TmPyPB) as the hole and electron transporting layers, respectively, Device A and Device B have been fabricated with the corresponding CIE coordinates of (0.32, 0.33) and (0.31, 0.34) at 9 V. Device B showed the maximum luminance of 364.66 cd·m-2 and the maximum current efficiency of 0.79 cd·A-1.
