Abstract
A series of pentacyclic analogs of alpha-quinquethiophene containing o ne or two furan or pyrrole units has been synthesized. The synthesis i s based on the cyanide-catalyzed Stetter reaction, providing the keton ic precursors to the pentacycles. Spectral and electrochemical investi gations show that the redox-stable mixed pentacycles display hypsochro mic shifts in their absorption maxima, as well as a greater ease of ox idation, in comparison to alpha-quinquethiophene.
