Synthesis and Photochromic Properties of a New Functionally Substituted Molecule Based on Spiropyran

Year: 2025

Type: article

Abstract: In this work, we report the synthesis of a new salt of photochromic spiropyran containing various functional groups and capable of reversibly reacting to external influences. It is shown that the synthesized spiropyran containing –CHO, –NO2, –OCH3, –(CH2)5PPh3 groups in its structure exhibits positive photochromism, as evi denced by its reversible photoinduced transformations under the action of ultraviolet and visible radiation. It is established that the presence of functional groups in the spirophotochrome molecule contributes to an increase in resistance to photodegradation.
