Donor–Acceptor Semiconducting Polymers Containing Benzodithiophene with Bithienyl Substituents

Synthesis and photovoltaic properties of two donor–acceptor polymers containing benzodithiophene with 3,3′,5-trihexylbithienyl substituents are reported. Benzo[c][1,2,5]thiadiazole and 5-hexylthieno[3,4-c]pyrrole-4,6-dione were used as acceptor building blocks for the synthesis of donor–acceptor pol...

Zusammenfassung:	Synthesis and photovoltaic properties of two donor–acceptor polymers containing benzodithiophene with 3,3′,5-trihexylbithienyl substituents are reported. Benzo[c][1,2,5]thiadiazole and 5-hexylthieno[3,4-c]pyrrole-4,6-dione were used as acceptor building blocks for the synthesis of donor–acceptor polymers. The photovoltaic properties of the synthesized donor–acceptor polymers were investigated in bulk heterojunction solar cells with [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) acceptor.
