Anthracene-based small molecules incorporating an electron accepting tricyanovinyl (TCV) group was prepared to investigate the linkage position influences of the anthracene and TCV groups on the opto-electrical and photovoltaic properties of the molecules. The maximum absorptions of the anthracene-based molecules incorporating the TCV group at the phenyl group of the triphenylamine unit (TCV-TpaA9
蒽基的小分子结合了电子接受三氰基乙烯基(TCV)的制备是为了研究蒽和TCV基团的键合位置对分子的光电和光伏性能的影响。在三苯胺单元的苯基上(TCV-TpaA 9,10 T,TCV-TpaTA 9,10 T和TCV-TpaA 2,6 T)或在噻吩单位(TpaA 9,10 T-TCV,TpaTA 9,10 T-TCV和TpaA 2,6 T-TCV被发现取决于蒽单元的连接位置。在三苯胺单元的苯基上含有TCV基团的分子的HOMO能级比在噻吩单元上的含有TCV基团的分子的HOMO能级高。溶液处理的小分子有机太阳能电池(SMOSC)具有ITO / PEDOT:PSS / TCV-TpaA 9,10 T或TCV-TpaA 2,6 T或TpaA 2,6 T-TCV:PC 71 BM(在AM 1.5辐照(100 mW cm -2)下,2:1 wt%)/ LiF / Al的最大能量转换效率分别为1.04%,1
