本文报道了一种具有大体积和柔性取代基的苝酰亚胺染料的等温荧光机械致色性。由机械刺激绘制的荧光图案可以通过热刺激、用溶剂蒸气处理或从橙色荧光到绿色荧光状态的自发结构转变来擦除。固体染料薄膜的等温荧光开关可应用于显示和传感材料。
Isothermally rewritable fluorescence mechanochromism has been realized for a perylene bisimide dye with bulky and flexible substituents. Fluorescent patterns drawn by mechanical stimuli can be erased by thermal stimuli, treatment with solvent vapors, or spontaneous structural transition from orange-fluorescent to green-fluorescent states. The isothermal fluorescence switching of solid dye films is applicable to displays and sensory materials.
