一种新型π共轭结构的咪唑衍生物的合成及其性质研究
Synthesis and Properties of a Novel Imidazole Derivative with π-Conjugated Structure
【摘要】 采用改进的固相W ittig反应,合成了一种新型的含有电子给受体和π共轭体系的咪唑衍生物———1-{反式-4-[4-(N,N-二甲基氨基)苯乙烯基]苯}咪唑(3),其结构经1H NMR,IR,MS和元素分析表征。用TG,UV和单光子荧光光谱研究了3的热稳定性和光学性质,结果表明3具有较高的热稳定性和优良的光学性质。
【Abstract】 A novel imidazole derivative with π-conjugated structure,1-[trans-4-(4-dimethylamino styryl) phenyl]imidazole(3),was synthesized by a modefied solvent-free Wittig reaction.The structure of 3 was characterized by ~1H NMR,IR,MS and elemental analysis.The properties of 3 were determined by TG,UV and single photon fluorescene spectrum.The results indicated that 3 exhibited excellent thermal stability and optical properties.
