Abstract: Abstract We designed and synthesized two new donor-acceptor (D-A) copolymers J46 and J47 through replacing thiophene conjugated side chains by thieno[3,2-b]thiophene (TT) in the benzo[1,2-b:4,5-b’]dithiophene (BDT) units copolymerized with fluorobenzotriazole (FBTA). J46 possesses alkyl substituent… read more here.
