摘要
以2-萘酚、苯肼和3-甲基-2-丁酮为原料,设计并合成了一种含萘环螺吡喃类光致变色化合物:1,3,3-三甲基吲哚啉螺萘并吡喃,通过1HNMR、IR和元素分析表征了它的分子结构,利用紫外光谱和荧光光谱对目标化合物的吸收光谱和光致发光光谱进行了研究,初步探索了目标产物的光致变色性能。吸收光谱结果表明,目标分子(闭环体)的二氯甲烷溶液(1×10-4mol/L)在可见光区基本无吸收而呈现无色,但经254 nm的紫外光照射后其开环体在480 nm处有较强的吸收而呈现红色(A=1.1),停止紫外光照射溶液恢复为无色,显示了良好的光致变色性能;发光光谱结果显示,目标分子经紫外光激发后其开环体在433 nm处有较强的蓝光发射。
Using 2-naphthol phenylhydrazine and 3-methyl-2-butanone as main raw materials, the title compound 1,3,3-trimethylindolinespironaphthopyran containing naphthalene ring was designed and synthesized through a series of reaction. Its chemical structure was characterized by ^1HNMR, IR and elementary analysis. By means of UV - vis and fluorescence spectrometers, the absorption and emission spectra of the title compound were studied and its photochromic properties were researched. The results indicated that the closed ring compound in CH2Cl2 （1×10^-4 mol/L） had almost no absorption in the region of visible light and looked like colorless, but on irradiation of 254 nm UV, the opening ring in CH2Cl2 had an intensive absorption （ A = 1.1 ） at 480 nm and gave a red color, but when stopping irradiation the solution returned colorless, indicating a good photochromic property. The fluorescence spectrum of the compound displayed an intensive blue emission light at 433 nm on UV irradiation.
