Abstract

Pyrrolo[3,4-c]pyrrole-1,3(2H,5H)-dione (1,3-DPP) was used as a building block to construct copolymers with a quaterthiophene unit. The resulting conjugated polymers showed rather high LUMO (the lowest unoccupied molecular orbital) levels of ca. −3.5 eV, compared to the polymers based on the well-known pyrrolo[3,4-c]pyrrole-1,4(2H,5H)dione (1,4-DPP) isomeric structure. These polymers exhibited promising p-channel charge transport performance with hole mobility up to 0.013 cm2 V−1 s−1 in organic thin film transistors.
