Abstract :

A novel alternating conjugated polymers, based on pyridine moieties, were synthesized via the Suzuki–Miyaura couple approach. Polymers were characterized by 1H NMR, gel permeation chromatography, UV–Vis spectroscopy, fluorescence and cyclic voltammetry. The luminescence of the copolymer exhibited extraordinary ight blue. The electrochemical study shows that the new alternating polymers do not merely have the properties of the two units that constitute it but has mutual hole and electron charge carrier properties which might be promising material for applications in high efficiency, single or low number layers functional devices.
