Fluorescent photochromic poly(methyl methacrylate) (PMMA) with spironaphthoxazine (SPO) and D-π-A type pyran-base fluorescent dye as a fluorophore was synthesized by typical free radical copolymerization. The poly(MMA-co-SPO-co-fluorophore) in both solution and solid film exhibited excellent photoregulated fluorescence switching behavior and reversible modulation of fluorescence intensity using alternating irradiation with UV and visible light. The poly(MMA-co-SPO-co-fluorophore) also showed viscosity and conductivity switching behaviors along with photoresponse.
具有螺噁嗪（SPO）和 D-π-A 型吡喃基荧光染料作为荧光团的荧光光致变色聚甲基丙烯酸甲酯（PMMA）通过典型的自由基共聚合成。聚（MMA-co-SPO-co-荧光团）在溶液和固体膜中均表现出优异的光调控荧光开关行为和荧光强度的可逆调节，使用紫外光和可见光交替照射。聚（MMA-co-SPO-co-荧光团）还表现出与光响应相关的粘度和电导率切换行为。
