The monomer, 3,6-bis(5-bromothiophen-2-yl)-2,5-bis(2-octyldodecyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione, contains a DPP moiety. DPP backbone derivatives as a strong acceptor unit, have a planar conjugated bicyclic structure engaging stronger π–π interactions which allows tuning the band-gap and energy-level of polymer organic semiconductors. Also long alkyl chains, namely 2-octyldodecyl, will allow better solubility for the polymer semiconductor and crystallization and aggregation capacity for the thin-film devices. DPP-containing polymers are considered promising materials for optimizing the performance of organic semiconductors.
