摘要
以2-羟基-1-萘甲醛和2,3,3-三甲基-3H-吲哚为主要中间体原料,设计并合成了一种含萘环的新型螺吡喃光致变色化合物,其化学结构通过1H NMR、IR和元素分析得到确证。该化合物在二氯甲烷溶液中经紫外光照射后由无色变为红色,停止照射又恢复为无色,表明目标化合物具有良好的光致变色性能,可以作为一类新型光致变色化合物进行应用性研究,为进一步开发具有良好性能的光致变色材料提供模型结构。
A new of spiropyran photochromic compound containing naphthalene ring was designed and synthesized by using 2-hydroxy-1-naphthaldehyde and 2,3,3-trimethyl-3H-indole as main raw materials. The molecular structures of the compound were characterized by IR, ^1H NMR and element analysis. The color of the compound in dichloromethane solution changed from colorless to red after irradiated by UV, and returned to colorless when the irradiation was stopped. The results indicated that the synthesized compound had a better photochromic property. This compound is a new promising photochromic material for practical application and a model structure for the study of efficient photochromic materials.
