萘并吡喃光致变色荧光开关研究进展

摘要

萘并吡喃及其衍生物是经典的光致变色材料,具有很低的背景颜色、优良的光致变色抗疲劳性、易于调控的变色动力学、开环体具有宽的吸收等优点,受到了研究者的重视.本文综述了近几年来作者课题组利用萘并吡喃构建光致变色荧光开关的研究进展,通过将荧光基团和萘并吡喃以掺杂模式、共聚物和有机小分子等形式构建光致变色荧光开关,研究了它们在溶液和薄膜中的荧光开关性能,初步探讨了萘并吡喃荧光开关在非破坏性读出和荧光成像等方面的应用潜能.%Naphthopyran and its derivatives are transitional photochromic materials with low background color,good resistance fatigue and fine contral over fading kinetics.Herein,we introduce the progress of the application of naphthopyran in photochromic fluorescence switching,including hazarding manner,polymers and organic molecules in solutions and films.These researches also explored the potential applications in nondestructive readout and fluorescent images.
