Benzodithiophene-2THBr-4EH
Benzodithiophene-2THBr-4EH, high purity monomer for applications in OPVs and OFETs
For the synthesis of low band-gap polymer semiconductors
1,3-Bis(5-bromo-4-(2-ethylhexyl)thiophen-2-yl)-5,7-bis(2-ethylhexyl)benzo[1,2-c:4,5-c']dithiophene-4,8-dione, or Benzodithiophene-2THBr-4EH, is a monomer for the synthesis of low band-gap polymer semiconductors such as PBDD4T and PBDD4T-2F. It has applications in OPV (fullerene or fullerene-free), tandem organic solar cells, and OFETs.
Benzodithiophene-2THBr-4EH has a more soluble structure due to its four branched side chains, so resulting polymers can be more easily processed for device fabrications.
