The monomer, 3,6-bis(5-bromothiophen-2-yl)-2,5-bis(2-octyldodecyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione, CAS Number 1260685-63-9, 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.
2,5-Bis(2-octyldodecyl)pyrrolo[3,4-c]pyrrole-1,4-(2H,5H)-dione-based donor-acceptor alternating copolymer bearing 5,5'-di(thiophen-2-yl)-2,2'-biselenophene exhibiting 1.5 cm2/Vs hole mobility in thin-film transistors.
Note: This product has been used in our own lab by Ossila chemist for the synthesis of PDPP4T and high mobility p-type polymer DPP-DTT.
