Preparation and Properties of Poly(methylpyridine-2,5-diyl)s

Abstract
A series of poly(methylpyridine-2,5-diyl)s were synthesized by dehalogenation polycondensation of the corresponding 2,5-dibromo-methylpyridine with zerovalent nickel complexes. The polymers had molecular weight much higher than that of poly(pyridine-2,5-diyl). Poly(methylpyridine-2,5-diyl)s were converted into semiconducting material by chemical and electrochemical reduction (n-type doping).
