摘要：

alpha-Thienyl or alpha-pyrrolyl groups were bonded to alpha-positions of benzo[2,1-b:3,4-b']dithiophene-4,5-dione via Stille coupling reactions followed by intramolecular benzoin condensations, giving a novel terameric pi-congugated oligomers. UV vis and elctrochemical studies for these oligomers indicate that the heterocyclic substituents selectively destabilize the HOMO-level to result in small HOMO-LUMO gaps.
