Synthsis of [1,2,5]thiadiazolo[3,4-C]pyridine: A Novel Analogue to BT

Heterocyclic electron-poor monomer [1,2,5]thiadiazolo[3,4-c]pyridine have been synthesized in high yields over five steps from readily available starting materials. The new deficient acceptor has good solubility in organic solvents so as to permit an appropriate coating process.
