摘要A 9,9 '-bifluorenylidene derivative, 2,2 ',2 '',2 '''-([9,9 '-bifluorenylidene]-2,2 ',7,7 '-tetrayltetrakis(4-octylthiophene-5,2-diyl))tetrakis(methanylylidene)tetrakis(3-oxo-2,3-dihydro-1H-indene-2,1-diylidene)tetramalononitrile (BF-TDCI4), was synthesized as an electron acceptor for organic photovoltaic cells. Its photophysical and electrochemical properties and thermal stability were investigated systematically. The photovoltaic devices were fabricated using PTB7-Th as the electron donor and BF-TDCI4 as the electron acceptor at various composition ratios. The optimized device exhibited a maximum power conversion efficiency of 4.35% with an open-circuit voltage of 0.87 V.
