摘要：
Three random conjugated polymers, RP-TiI, RP-2TiI and RP-TVTiI based on both thieno[3,4-c]pyrrole-4,6-dione and isoindigo units have been synthesized by Stille cross-coupling reaction. The optical and electrochemical properties of new polymers have been investigated. The resulted polymers showed broad absorption spectra and appropriate energy levels for polymer solar cell applications. The bulk heterojunction devices based on the blend of the polymer RP-TiI and PC61BM showed a power conversion efficiency of 1.75%.
