二芳烯类光致变色化合物的合成及其性质
Synthesis and Photochromism of Diarylethenes in PMMA Amorphous Film and in Solution
摘要
Abstract
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.关键词
