3,6-Bis(5-bromo-2-thienyl)-2,5-bis(2-hexyldecyl)-2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione

3,6-Bis(5-bromo-2-thienyl)-2,5-bis(2-hexyldecyl)-2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione (DDP-Br₂) belongs to the series of diketopyrrolopyrrole (DPP) based materials which show hole or ambipolar transport behavior with mobilities of charge carriers in the range of 0.1-1 cm²V^-1 s^-1. It has an electron deficient core that forms a low LUMO energy level which facilitates better air-stability for n-type organic semiconductors.

DDP-Br₂ can be used in the fabrication of a variety of opto-electronic devices such as organic field effect transistors (OFETs), perovskite based solar cells, non-fullerene organic solar cells.

Novel acceptors utilized in low band gap polymer cells and showed optical bandgaps ranging from 1.81 to 1.94 eV and intense absorption bands that cover a wide range from 300 to 700 nm
