摘要: 合成了含噁唑环的俘精酸酐,4-(5-甲基-2-对甲氧苯基-4-乙酰基唑)乙叉(异丙叉)丁二酸酐,研究了该化合物在不同溶剂中的光致变色性能,进行了光成色和光消色过程的动力学研究,并考察了溶剂极性对该化合物吸收光谱的影响.稳态动力学分析结果表明,该化合物呈色体的光消色反应遵循一级动力学规律,俘精酸酐本身的光反应比较复杂,不符合简单的动力学级数.

Abstract: 4-[5-Methyl-2-(p-methyloxyphenyl)-4-acetyloxazoly]ethylidene(isoproylidene) succinic anhydride was synthesized by Stobbe condensations of 4-acetyl-5-methyl-2-(p-methyloxyphenyl) oxazole with diethyl 2-isopropylidene succinate in toluene, in the presence of sodium hydride, followed by cyclization of diacid by treatment with acetyl chloride. The photochromic properties of the fulgide in various solvents were studied. The solvent effects on the absorption spectra were also investigated. The analysis results obtained by steady state kinetics show that the photodecoloration of the colored form followed the first-order kinetics. The photocoloration reactions were more complicated and did not fit simple kinetics.

Key words: Fulgide, Photochromism, Absorption spectra, Kinetics
