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.
有机光致变色材料一直是科学家们关注的热点，这归因于其广泛的应用和光调控多色光致发光的特性。同时，近年来，有机材料的白光发射也引起了相当大的关注。在此，将这两个概念结合在一起，在具有白光发射的光致变色共聚物中取得了一项成就。合成了一种由四苯乙烯（TPE）和螺吡喃（SP）单体组成的新型无定形聚丙烯酰胺共聚物，该共聚物能够发射包括具有国际照明委员会（CIE）坐标（0.33，0.33）的白光在内的可调色荧光。这一新概念为获得白光发射材料提供了一种可行的方法，这将对其进一步发展产生深远的影响。
