摘要: 在同一分子中既含有电子给体基团,又含有电子受体基团的单体,如甲基丙烯酸二甲氨基苄酯(DMABMA),N-(4-N′,N′-二甲氨基苯基)代丙烯酰胺(DMAPAA)及其聚合物的荧光光谱颇为有趣。

Abstract: The fluorescence spectra of 8-acryloxyqulnoline (AQ) and 8-methacryloxyquinoline (MAQ), and their polymers in dimethylformamide were recorded. It was found that the fluorescence intensity of these monomers are weaker than that of their corresponding polymers. Due to the electron donor moiety of quinolyl and electron acceptor moiety of acrylic double bond exist in the same molecule, the "structural self-quenching effect" of these monomers would be suggested. These monomers could be polymerized easily under the irradiation of ultraviolet radiation.

Key words: 8-acryloxyquinoline, fluorescence spectra, structural self-quenching effect
