Novel acrylate copolymer with carbazole pendant groups and derivatives of bipyridine as side chains were synthesized, in which derivatives of bipyridine as electro-optic chromophores and carbazolyl as pho-toconductive moiety were covalently linked to the acrylate back-bone. 2–(9–Carbazolyl)ethyl methacrylate (CEM) and 2-methyl-acrylic acid 2- {4,4’-dimethyl-5’-[2-(5-methyl-thiophen-2-yl)-vinyl]-[2,2’]bipyridinyl-5-yl}-ethyl ester (BiPy) were synthesized and then copolymerized to give (99:1), (98:2), and (92:8 mol/mol) CEM/BiPy copolymers. Solutions of the copolymers in dioxane were examined for their photoluminescence properties.
