摘要：

A facial synthetic route to a new heteroheptacene with the inclusion of carbazole and thiophene units is described. The synthesis of two new semiconducting copolymers with use of the heteroheptacene unit is also reported. The introduction of heteroatoms (sulfur, nitrogen) in the fused-ring system leads to small optical band-gaps of these polymers. The charge carrier mobilities for these polymers are measured in ambient conditions which are sufficient for photovoltaic applications.
