Synthesis and Properties of Novel Photochromic Dyads Based on Spiropyrans and Schiff Base
摘要
Abstract
A series of novel photochromic compounds (4a-4n) based on spiropyrans and Schiff base were synthesized. Their structures were characterized by 1H NMR, IR, and HRMS. The compounds were proved by UV measurement to have excellent photochromic properties both in organic solutions and in PMMA polymer films. The thermal decay process of the representative compound 4a in methanol, and compounds 4a, 4f in PMMA polymer films were also studied. The color of compound 4e differed from other compounds. Its merocy-anine form exhibited rare green color. The representative compound 4a show good fluorescence properties in dichloromethane solution. The results showed that the novel photochromic compounds based on spiropyrans and Schiff base have excellent photochromic properties in methanol, dichloromethane, cyclohexane solution, and PMMA polymer films. These properties are great helpful for their potential application in the field of multifunction material.关键词
