Abstract:
Organic photochromic materials have always been a hot topic among scientists, ascribed to its broad applications and characteristic properties of photo-modulating multicolor photoluminescence. Meanwhile, white-light emission of organic materials has drawn considerable attention in recent years. Herein, these two concepts are combined together to make an achievement in a photochromic copolymer with white-light emission. A novel amorphous polyacrylamide copolymer consisting of tetraphenylethylene (TPE) and spiropyran (SP) monomers is synthesized, which is capable of emitting fluorescence with tunable colors including white-light one with Commission Internationale de L'éclairage coordinates (0.33, 0.33). This new concept provides an available approach to obtain white-light emission materials which will exert far-reaching influence in its further development.
