Description

General description

PBDT-TBP is a conducting polymer with benzodithiophene (BDT) donor groups and thieno[3,4-c]pyrrole-4,6(5H)-dione acceptor groups. It has π bridges that can be synthesized by palladium (Pd) catalyzed Stille-coupling. These π-conjugations are used to enhance the optical and electrochemical properties of the polymer.
