Synthesis of polymers alternating 3-alkylthiophene oligomers and 2,2′-bipyridine

Structurally defined, all conjugated polymers were chemically synthetized using the Stille cross-coupling reaction. Their structure consisted in an alternation of 2,2′-bipyridine and regioregular 3-octylthiophene oligomers which contained 4 or 6 thienyl rings. The NMR. UV-Visible and electrochemical characterisations are also reported.
