Abstract

Photochromic compounds of the spiropyran family have two main isomers capable of inter-switching with UV or visible light. In the current review, we discuss recent advances in the synthesis, investigation of properties, and applications of spiropyran derivatives. Spiropyrans of the indoline series are in focus as the most promising representatives of multi-sensitive spirocyclic compounds, which can be switched by a number of external stimuli, including light, temperature, pH, presence of metal ions, and mechanical stress. Particular attention is paid to the structural features of molecules, their influence on photochromic properties, and the reactions taking place during isomerization, as the understanding of the structure–property relationships will rationalize the synthesis of compounds with predetermined characteristics. The main prospects for applications of spiropyrans in such fields as smart material production, molecular electronics and nanomachinery, sensing of environmental and biological molecules, and photopharmacology are also discussed.

螺旋吡喃的现代视角:从单分子到智能材料
螺吡喃家族的光致变色化合物有两种主要的同分异构体,能够与紫外线或可见光相互交换。本文综述了近年来螺吡喃衍生物的合成、性质研究和应用等方面的研究进展。吲哚系的螺吡喃类是多敏感螺环化合物中最有前途的代表,它可以通过许多外部刺激(包括光、温度、pH、金属离子的存在和机械应力)进行切换。特别关注分子的结构特征,它们对光致变色性质的影响,以及异构化过程中发生的反应,因为对结构-性质关系的理解将使具有预定特性的化合物的合成合理化。展望了螺吡喃类化合物在智能材料制造、分子电子学与纳米机械、环境与生物分子传感、光药理学等领域的应用前景。图形抽象

期刊介绍: Topics in Current Chemistry is a journal that presents critical reviews of present and future trends in modern chemical research. It covers all areas of chemical science, including interactions with related disciplines like biology, medicine, physics, and materials science. The articles in this journal are organized into thematic collections, offering a comprehensive perspective on emerging research to non-specialist readers in academia or industry. Each review article focuses on one aspect of the topic and provides a critical survey, placing it in the context of the collection. Selected examples highlight significant developments from the past 5 to 10 years. Instead of providing an exhaustive summary or extensive data, the articles concentrate on methodological thinking. This approach allows non-specialist readers to understand the information fully and presents the potential prospects for future developments.
