摘    要:我们曾报道过N-丙烯酰-N′-苯基哌嗪(APP)的合成、聚合、荧光性质及其单独或与过氧化物构成氧化还原体系以引发烯类单体聚合的研究。由于APP是分子中含有给电子生色基团和缺电子双键的丙烯酸类衍生物,其荧光表现有结构自猝灭现象并且聚合物的荧光也能被其它缺电子烯类单体如丙烯腈所淬灭。对于分子中含有多个氮原子的芳杂环叔胺丙烯酸类单体的研究,文献报道较少。本文合成了新的功能性单体N-甲基丙烯酰-N′-嘧啶基哌嗪(MPMP),并观察了单体及其聚合物溶液的荧光光谱。

关 键 词:N-甲基丙烯酰-N’-嘧啶哌嗪  含胺基功能性单体  结构自猝灭现象  荧光光谱  激基复合物  e-值  Stern-Volmer常数

Abstract:A novel acrylic monomer bearing pyrimidino-moiety, N-methacrylyl-N'-pyrimidinopipe-razine (MPMP) was synthesized by the reaction of N-pyrimidinopiperazine and methacrylyl chloride in the presence of triethylamine. Both absorption and fluorescence spectum for the monomer and its polymer were recorded. It was observed that the fluorescence intensity of monomeric MPMP was slightly lower than that of its polymer. The monomer did not dramatically appear its structural self-quenching effect as we have reported previously. The fluorescence of the polymer, P(MPMP) could be quenched by electron-deficient quenchers such as methacrylonitrile, acrylonitrile, fumaronitrile; methyl acrylate and methyl methacrylate. The Stern-Volmer constants of those quenchers for P(MPMP) were determined.
Keywords:N-Methacrylyl-N'-pyrimidinopiperazine   Fluorescence spectra   Absorption spectra   Structural self-quenching effect
