Applications

As a family member of polythiophenes, PBDD4T has a backbone consisting of repeating benzodithiophene-4,8-dione and α-quaterthiophene units. π electrons can be delocalized effectively through the alternative electron push?pull effect, resulting a low band-gap polymer. Also, with four ethylhexyl branched side chains, the polymer is more soluble in most of organic solvents.

We also have PBDD4T-2F available which allows fluorine-fluorine interaction at the polymer back-bone structure for device film morphology control. Both PBDD4T and PBDD4T-2F are used for highly efficient fullerene and non-fullerene including such as ITIC and P(NDI2OD-T2F) as acceptors for OPV devices.
