Conjugated materials containing dithieno3,2-b:2′,3′-dpyrrole and its derivatives for organic and hybrid solar cell applications

Dithieno3,2-b:2′,3′-dpyrrole (DTP) and its derivatives have occupied an important position in both electron-rich and electron-deficient building blocks to construct photovoltaic materials. Here, we highlight the exciting progress of donors based on original DTP,N-acyl DTP and fused DTP and acceptors based on lactam and imide, respectively.
