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.
