摘　　要：以3-甲基吲哚和亚异丙基丁二酸二乙酯为起始原料,经过六步反应合成N-羟丙基-2-吲哚基俘精酰亚胺.紫外-可见吸收光谱表明,该俘精酰亚胺在不同溶剂中呈现出不同的最大吸收波长,且在非质子型溶剂中显示了可逆的光致变色性,在光致变色服装材料的制备中具有一定的应用价值.With 3-methyl indole and isopropylidene diethyl succinate as the starting materials, the E isomer of N-hydroxypropyl-2-indolyl fulgimide, a photochromic compound, was synthesized through six steps. The molecular structure of the synthesized intermediates and the finally product was confirmed by ESR and MS analysis. Upon exposure to 450 nm light, the E isomer could be transformed to C isomer. The UV-visible absorption spectra of the two isomers in different solvents （water/ethanol, cyanide, toluene and n-hexane） were measured. The wavelength of the maximum absorption of the E isomer was in the range of 373 - 388 nm. That of the C isomer was in the range of 486 - 556 nm. In aprotie solvents, conversion between the E and the C isomer is reversible. These findings indicate that the E isomer of N-hydroxypropyl-2-indolyl fulgimide may find applications in the prepara- tion of photochromic clothing materials.
