Abstract:

As a kind of stimuli-responsive molecules,light-responsive molecules have been widely used in smart materials,light-controlled devices and other fields due to their advantages of signal stability,remote control,transient and environmental protection.Among them,the most typical and widely studied are photoisomeric molecules.The structure of photoisomeric molecules change under specific wavelengths of light,sometimes with macroscopic color changing.Under another wavelength of light,the structure reverts back to their original structure and the color fade.The synthesis and preparation of spiropyran,azobenzene,diaryl ethylene and other mainstream photoisomeric molecules,the light response mechanism and their applications in practical production and life such as salt lake resource extraction,drug detection and energy storage material preparation were reviewed.The development trends of photoresponsive molecules in low-cost and environment-friendly synthesis,composite functional materials,intelligent molecular devices and so on were prospected.

Key words: light stimulation, photoresponsive molecules, photochromism, photoisomerization
