Abstract

Poly(bithiophene) dervatives unsymmetrically substituted with strong electron-donating groups and strong electron-withdrawing groups (e.g. see Fig.) have been synthesized. The substituents induce electronic push–pull effects along the conjugated chain which could be exploited in the design of organic-based multiple quantum well structures
