本论文合成了三种新的二芳基乙烯类光致变色化合物1-(2,5二甲基噻吩-3-基),2-[2-甲基-5-(4-甲氧苯基噻吩)-3-基]全氟环戊烯(1a),1-(2,5二甲基噻吩-3-基),2-[2-甲基-5-(4-乙氧苯基噻吩)-3-基]全氟环戊烯(2a),1-(2,5二甲基噻吩-3-基),2-[2-甲基-5-(4-氯苯基噻吩)-3-基]全氟环戊烯(3a),并且研究了它们的光电特性.实验结果表明这些二芳烯化合物在溶液和PMMA膜片中均具有良好的光致变色性能.在313nm紫外灯的照射下,这些二芳烯化合物的溶液和PMMA膜片均由无色变为蓝色,在适当波长可见光照射下,它们均从有色态返回到无色态.在不同的溶液和PMMA膜片中,这些化合物在它们各自的激发波长的照射下均显示出较强的荧光.在313nm紫外灯的照射下,二芳烯由开环态变为闭环态,荧光强度逐渐降低.

Three new photochromic diarylethenes, 1-(2, 5-dimethylthien-3-yl), 2-[2-methyl-5-(4-methoxyphenylthien) -3-yl]perfluorocyclopentene (1 a), 1- (2,5- dimethylthien-3-yl), 2- [2- methyl-5- (4-ethoxyphenylthien) -3-yl] perfluorocyclopentene (2a) and 1 - (2,5-dimethylthien-3-yl), 2- [ 2-methyl-5- ( 4-chlorophenylthien )-3-yl ] perfluorocyclopentene ( 3a ), were synthesized and their photochemical properties were investigated in detail. The results indicate that these diarylethenes showed good photochromic behavior both in solution and in poly( methyl methacrylate) (PMMA) amorphous film. Under irradiation with 313 nm light, the colorless of the hexane solution and the PMMA film turned colored and under the visible light irradiation (λ＞510 nm) the colored hexane solution and the colored PMMA film can return to colorless. All of them exhibited good fluorescence in different solution and in PMMA film excited by their respective excitation wavelength, and their fluorescence intensity decreased along with the photochromism from open-ring form to closed-ring form under irradiation with 313 nm UV light.
