PBDT
PBDt, often written as PBDT, refers to polybenzodithiophene, a family of conjugated polymers based on the benzodithiophene (BDT) unit. These polymers are built from benzodithiophene cores linked to various co-monomers to form alternating or copolymer backbones. The BDT unit provides planarity and strong pi-conjugation, which support charge transport in solid films.
In synthesis, PBDT polymers are typically prepared by palladium-catalyzed cross-coupling polymerization methods such as Suzuki or
Properties of PBDT polymers include strong absorption in the visible to near-infrared region, tunable HOMO and
Applications for PBDT-based materials span organic electronics, particularly as donor components in organic photovoltaic cells, as
Derivatives of PBDT involve modifying the backbone with various co-monomers or functional groups to tune optical
