Influence of heteroaryl group on electrochemical and spectroscopic properties of conjugated polymers

During our search for novel conjugated compounds, novel monomers and their polymers with selenophene and tellurophene group were synthesized and characterized. Conjugated poly(p-phenylenevinylenes)s (PPV) derivatives attracted a large attention due to their photolouminescence properties. The stereocontrolled synthesis of 1,4-bis(2-(heteroar-2-yl) ethenyl)benzenes and 1,4-bis(heteroar-2-yl)benzenes with tellurophene, selenophene, thiophene and furan-based monomers has been successfully performed. Eight of p-phenylene derivatives have been synthesized, electrochemically polymerized and characterized. (C) 2012 Elsevier Ltd. All rights reserved.
