PBDB-T-2Cl is part of the PBDB-T polymer family. It has a high OPV device performance, with reported efficiencies exceeding 12%. PSCs based on PBDB-T-2Cl as the donor and ITIC-2F as the acceptor have achieved a power conversion efficiency (PCE) of over 14% [2].

Compared to PBDB-T-2F, PBDB-T-2Cl showed slightly lower calculated HOMO levels. Although fluorine has greater electronegativity, it is believed that electron density can be delocalised more effectively to the chlorine atom than the fluorine atom on the BDT (benzodithiophene) backbone unit, resulting in a deeper HOMO energy level.

Luminosyn™ PBDB-T-2Cl

Luminosyn™ PBDB-T-2Cl (also referred to as PCE14) is now available.

High purity
PBDB-T-2Cl is purified via Soxhlet extraction with acetone, hexane and chlorobenzene under an argon atmosphere
