Dithieno[2,3-d:2′,3′-d′]naphtho[1,2-b:3,4-b′]dithiophene – a novel electron-rich building block for low band gap conjugated polymers†
Abstract
A feasible synthesis of 10,11-di(3,7-dimethyloctyloxy)dithieno[2,3-d:2′,3′-d′]naphtho[1,2-b:3,4-b′]dithiophene (NDT) was presented, and a novel low band gap (LBG) NDT-based polymer was prepared and characterized. The preliminary results indicate that NDT can be used as a novel electron-rich building block in the development of LBG conjugated polymers.
