ABSTRACT

A low band gap polymer based on thieno[3,4-b]thiophene (TT) and cyclopentadithiophene (CPDT), named as P-TT, was synthesized through palladium-catalyzed Stille coupling reaction. Due to the strong electron-donating property of CPDT and quinoidal structural TT, P-TT exhibited narrow band gap (1.30 eV). Optical and thermal properties of P-TT had been investigated.
