It is an object of the present invention to provide a copolymer that can be used as a semiconductor material and is highly stable in solution. The problem is solved by a copolymer containing a repeating unit having a dioxopyrrole condensed ring skeleton and a repeating unit having a dithieno condensed ring skeleton and also having a specific substituent.
本发明的目的是提供一种可用作半导体材料且在溶液中高度稳定的共聚物。要解决这个问题,就需要一种共聚物,该共聚物含有一个具有二氧
吡咯缩合环骨架的重复单元和一个具有二
噻吩缩合环骨架的重复单元,并且还具有一个特定的取代基。
