SYNTHESIS, POLYMERIZATION AND FLUORESCENCE BEHAVIOR OF N-(2-VINYLOXYETHYL)-1,8- NAPHTHALIMIDE AND ITS POLYMER
N-(2-乙烯氧乙基)-1,8-萘二甲酰亚胺聚合物与共聚物的荧光行为

A novel functional monomer N-(2-Vinyloxyethyl)naphthalimide(VOENl) was synthesized and the photochemical behavior of its polymer was studied. With the electron-donating viny-loxyethyl group and the electron-accepting naphthalyl chromophore moiety coexisting in the same molecule, VOENI would form exciplex intermolecularly upon UV-irradiation and showed much lower fluorescence emission intensity compared with its polymer. Such a phenome-num was also termed as "Structural Self-Quenching Effect" similar to what had been reported previously in those structurally reversed cases of acrylic monomers bearing both electron-donating chromophore moiety and electron-accepting double bond in one molecule.
