✦ Synopsis

on the occasion of his 60th birthday Thiophene-based p-conjugated oligomers and polymers have recently emerged as very promising organic devices for electronic and optical technologies. The optoelectronic properties of these materials vary with the degree of extended conjugation and the inherent electron density of the pconjugated backbone. A recent strategy to modulate these two parameters involves the synthesis of macromolecules featuring more than one type of conjugated-ring unit along the main chain. Increased conjugation can be achieved in alternating copolymers such as A (Scheme 1) because of an intramolecular charge transfer (ICT) from the electron-donor thienyl to the electron-acceptor pyridinyl moieties.
