Abstract

Abstract A new electron deficient unit, dimethyl-2H-benzimidazole (MBI), and dihydroindeno [2, 1-a] indene (ININE) moiety as electron-rich unit were coupled to synthesize the conjugated polymers containing electron donor–acceptor pair for organic photovoltaics. ININE, MBI, and thiophene (or bithiophene) units were incorporated using Stille and Suzuki polymerization to generate poly (2, 7-(5, 5, 10, 10-tetrakis (2-ethylhexyl)-5, 10-dihydro- ...
