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.

光调制多色光致发光，包括来自光致变色共聚物的白光发射

有机光致变色材料一直是科学家们的热门话题，这归因于其广泛的应用和光调制多色光致发光的特性。同时，近年来有机材料的白光发射引起了相当大的关注。在这里，将这两个概念结合在一起，从而在具有白光发射的光致变色共聚物中取得了成就。合成了一种新型的由四苯基乙烯（TPE）和螺吡喃（SP）单体组成的无定形聚丙烯酰胺共聚物，该共聚物能够发出具有可调色的荧光，包括具有国际照明委员会（0.33，0.33）的白光。
