摘要: 实现螺吡喃固态光致变色对于其在分子开关、逻辑门、信息存储等领域具有重要的意义,然而由于缺乏螺吡喃异构化所需的充足自由空间,对于固态/晶体状态下实现螺吡喃的可逆光致变色的研究还鲜有报道。在本工作中,通过在螺吡喃吲哚氮原子部位引入柔性烷基链,以提高螺吡喃分子之间的异构化所需的自由空间。同时,通过季铵化反应,引入3种不同的铵盐头部,可以提供活泼的结合位点,以进一步扩展螺吡喃分子的应用领域。所制备的3种螺吡喃阳离子表面活性剂不管是在溶液中还是固体状态下均可以实现有效的可逆变色,这有望为新型光敏复合材料领域的发展提供新的选择。

Abstract: The realization of solid-state photochromism for spiropyrane is of great significance in the fields of molecular switches, logic gates, information storage, etc. However, due to the lack of sufficient free volume required for isomerization of spiropyrane, there are few reports on the research of realizing reversible photochromism in solid/crystal state for spiropyrane. In this paper, a flexible alkyl chain is introduced at the nitrogen atom of spiropyrane indole to increase the free volume required for isomerization of spiropyrane. Meanwhile, the introduction of three different ammonium salt heads through the quaternization reaction can provide active binding sites to further expand the application field of spiropyrane. the prepared three spiropyrane cationic surfactants can achieve effective reversible color changes in solution and in solid state,Which are expected to provide new choices for the development of new photosensitive composites.


Key words: spiropyrane; surfactant; solid-state photochromism
