摘要
合成了6-硝基-1,′3,′3′-三甲基吲哚啉螺苯并吡喃,通过红外光谱和元素分析确证其结构,并研究了闭环体与开环体的光致变色性能,解释了在不同溶剂介质中紫外吸收光谱的溶剂效应,并比较褪色反应速率常数的差异.
In this paper, indolin spiropyran were synthesized. It has been identified by IR spectra and elemental analysis. The photochromic properties of bisspirocyclic compounds and their ring opening form were studied.
