Progress of Selenophene Polymers and Oligomers Based Organic Optoelectronic Materials

主要从光电性能角度总结了近几年硒吩聚合物/寡聚物在有机太阳能电池(OSCs)、场效应晶体管(FETs)、发光二级管(LED)等方面的研究进展。目前,基于聚硒吩并[3,4-b]硒吩-苯并二硒吩(PSeB2)(polyselenopheno[3,4-b]selenophene-co-benzodiselenophene)本体异质结太阳能电池器件的能量转化效率最高,达6.87%;场效应晶体管方面,基于PSeDPP(P28)器件的空穴迁移率最高达1.62cm2.V-1.s-1。基于PFO-DDSTQ(一种硒吩芴基聚合物)的发光二级管,表现出目前基于硒吩化合物的最长波长发光器件,EL光谱峰值约860nm。通过对研究者的研究成果的总结发现,在有机光电器件的应用领域中硒吩聚合物/寡聚物是一种极具应用前景的材料。

In recent years, many researchers have an increasing interest in selenophene based polymers and oligomers in organic optoelectronic devices. So far, organic solar cells based on polyselenopheno l-3, 4-b] selenophene-co- benzodiselenophene（PSeB2） show higher power conversion efficiency of 6.87 % , field-effect transistors based on PSeDPP （P28）, consisting of selenophene and 3,6-dithiophen-2-yl-2,5-dialkylpyrrolo[-3,4-c]pyrrole-1,4-dione （DPP）, show higher hole mobility of 1.62cmZ/（Vs）. PLED device based on PFO-DDSTQ show near infrared emission at 860nm. This paper summarizes the progress of selenophene polymers and 01igomers based organic optoelectronic devices.
