Abstract

Abstract A new series of 2, 1, 3-benzothiadiazole (BT) acceptors with different conjugated aryl-vinylene side chains have been designed and used to build efficient low-bandgap (LBG) photovoltaic copolymers. Based on benzo [1, 2-b: 3, 4-b′] dithiophene and the resulting new BT derivatives, three two-dimensional (2D)-like donor (D)–acceptor (A) conjugated copolymers have been synthesised by Stille coupling polymerisation. These ...
