【Abstract】 Conjugated copolymer P-1 and P-2 were obtained by the polymerization of 4,8-dibromo-1,5-dibutoxynaphthalene (M-I) and 1,4-divinyl-2,5-dibutoxybenzene (M-Ⅱ), 4,8-dibromo-1,5-dibutoxynaphthalene (M-Ⅰ) and 4,4′-divinylbiphenyl (M-Ⅲ) through Pd-catalyzed Heck reaction. Both monomers and polymer were characterized by NMR, MS, FT-IR, UV, Cyclic voltammetry, fluorescent spectroscopy and so on. Naphthyl unit is a good chromophore. The copolymers possess good solubility in common solvents due to the presence of alkoxyl substituents in the molecular chains. The copolymers P-1 and P-2 can emit very strong green fluorescence. They are expected to have potential application in the materials of electro-optical molecular sensors.更多还原
