Stimuli-responsive polymers have received growing attention in the photochromic area of applied materials undoubtedly. It remains a great challenge to achieve multifunctional luminescence materials with a multitudinous stimuli response. Three color-convertible copolymers are obtained with the relative copolymerization of benzaldehyde, 2,5-dihydroxy terephthalate, spiropyran (SP), and acrylamide. The achieved solid powder could respond to light, temperature, as well as humidity upon the alternation of UV light and visible light irradiation. Multicolor conversions including white-light emission with CIE coordinates (0.33, 0.33) are also obtained reversibly owing to the photochromic nature of SP moiety. Furthermore, the energy transfers proposed in these photochromic copolymers are not limited to fluorescence energy transfer only, which are enriched by triplet energy transfer with long lifetimes. Corresponding properties and applications were also fully explored based on these copolymers.

多响应纯有机共聚物的可调荧光和室温磷光

毫无疑问，刺激响应性聚合物在应用材料的光致变色领域受到越来越多的关注。实现具有多种刺激响应的多功能发光材料仍然是一个巨大的挑战。通过苯甲醛，2,5-二羟基对苯二甲酸对苯二甲酸酯，螺吡喃（SP）和丙烯酰胺的相对共聚反应，获得了三种颜色可转换的共聚物。当紫外线和可见光交替照射时，所获得的固体粉末可以响应光，温度和湿度。由于SP部分的光致变色性质，还可逆地获得包括具有CIE坐标（0.33，0.33）的白光发射的多色转换。此外，在这些光致变色共聚物中提出的能量转移不仅限于荧光能量转移，长寿命的三重态能量转移丰富了这些元素。基于这些共聚物也充分探索了相应的性质和应用。
