摘要
以香兰素和邻苯二胺为原料合成了席夫碱,以质谱和核磁等手段进行了结构表征。该化合物有较好的光致变色性,其分子结构在紫外-热或者酸-碱作用下,可发生可逆循环变化过程。文中探讨了紫外、热、酸碱度对化合物结构的影响,及其引起的光谱性质的变化,结果表明,它有望应用于信息存储材料领域。
A Schiff base was synthesized from the condensation reaction between o-phenylenediamine and vanillin. It was characterized by MS and NMR. Its photochromic properties were investigated through UV-Vis and fluorescence spectra. The influence of UV irradiation,heat,and acidity on the structure and spectral properties of the compound were investigated. The results showed that its molecular structure underwent reversible changes upon UVheat or acid-base treatment. It may be used as an information storage material.
