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, ...
