摘　　要：合成了两种新的二芳基乙烯类光致变色化合物1,2 双(2 甲基5 (4 乙氧基苯基)噻吩3 基)全氟环戊烯(1a)和1,2 双(2 甲基5 (对氟苯基)噻吩3 基)全氟环戊烯(2a),并且研究了其在不同溶剂和浓度中的UV Vis光谱、荧光性质和光致变色反应动力学特征.实验结果表明,化合物1a和2a具有良好的光致变色性质和较强的荧光;光致变色闭环反应为零级反应,开环反应为一级反应.Two novel photochromic dithienylethenes compounds, 1,2-bis[2-methyl-5-(4-ethoxyphenyl)-3-thienyl] perfluorocyclopentene (1a) and 1, 2-bis[2-methyl-5(p-fluorophenyl)-3-thienyl] perfluorocyclopentene (2a) were synthesized, and their UV-Vis absorption spectra, fluorescent properties and photochromic dynamics character were studied in different solvents and concentrations. The results indicate that they have not only shown good photochromic behavior and strong fluorescent properties, but also their cyclization reactions are zeroth order reaction and cycloreversion reactions are first order reaction.
