Synthesis of all-conjugated donor acceptor block copolymers and their application in all-polymer solar cells

Electron donor-acceptor triblock and diblock copolymers have attracted considerable interest due to their potential applications in all-polymer solar cells as single-active components or surfactants. However, the number of donor-acceptor block copolymers has lagged behind that of the rod-coil and rod-rod block copolymers due to their synthetic difficulties. This minireview highlights the recent advances in the synthetic strategies for the all-conjugated donor-acceptor block copolymers and their application in all-polymer solar cells.
