Triarylamine derivatives which have outstanding photoelectric function make them as attractive electron donor materials in organic solar cells (OSCs). Especially, star-shaped organic molecules with electron-rich triarylamine core and two-dimensional conjugated polymers having electron-rich donor-π-bridge-acceptor side chains exhibit promising performance in bulk heterojunction solar cells (BHJs). Despite the intensive research has been carried out on triarylamine based donor materials, there are only few papers about alternating D-A copolymer including triarylamine units. Herein we report the new alternating copolymers based on electron-rich triarylamine units. |
