As a family member of polythiophenes, PBT1 (also known as 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 OPV devices using fullerenes and non-fullerenes such as ITIC and P(NDI2OD-T2F) as acceptors.
Luminosyn™ PBT1 is now available.
