Two methacrylate monomers containing highly fluorescent phenylene vinylene and carbazolyene vinylene moieties were synthesized. Fluorescent side-chain polymers with potential electroluminescent device application were obtained by copolymerization of these monomers with methyl methacrylate (MMA) or 9-vinylcarbazole (NVK) using a free radical initiator. Since the polymers were very soluble in common organic solvents, polymeric films could be prepared by spin coating or casting. The molecular weight of the polymers was found to be as high as 40,000 g/mol and the glass transition temperature (T_g) varied from 120℃ to above 200℃, depending on the chemical structure of the polymers. The phenylene vinylene-based polymers showed greenish-blue emission (around 485 nm) and the carbazolylene vinylene-based polymers blue emission (around 445 nm).
