提出了1′-丙烯酰氯-3 ′，3 ′-二甲基-6-硝基-螺（2 H-1-苯并吡喃-2，2 ′-吲哚啉）（SPMA）修饰的光响应和光响应聚合物光子晶体（PC），并通过SPMA修饰的PC与图案化石墨层的结合实现了其动态显示图案.这些PC在紫外光照射下表现出荧光，因为SPMA的异构化，这是限制在壳的聚合物胶体球。在图案化石墨层上施加电压后，特定区域中的PC的荧光消失，获得动态显示图案。在紫外光照射下，PC从“部分荧光”状态变为初始“荧光”状态，并且图案消失。利用该技术，在玻璃基片上制作了“ML N”的PC图形，在纸基片上制作了“0”到“9”的PC图形。因此，这些双响应PC在信息记录、防伪、动态显示和光电器件方面具有潜在的应用。
Light and electrothermal responsive polymer photonic crystals (PCs) modified with 1′‐acryloyl chloride‐3′,3′‐dimethyl‐6‐nitro‐spiro(2H‐1‐benzopyran‐2,2′‐indoline) (SPMA) are proposed, and their dynamic display patterns are achieved through the combination of the SPMA‐modified PCs and a patterned graphite layer. These PCs exhibit fluorescence under UV light irradiation because of the isomerization of the SPMA, which is restricted in the shell of the polymer colloidal spheres. After a voltage is applied to the patterned graphite layer, the fluorescence of PCs in the specific area disappears, and dynamic display patterns are obtained. Under UV light irradiation, the PCs change from the “partial‐fluorescence” state to the initial “fluorescence” state, and the patterns disappear. Using this technique, the PC pattern “M L N” on the glass substrate and PC patterns from “0” to “9” on the paper substrate are fabricated. Thus, these dual‐responsive PCs have potential applications in information recording, anticounterfeiting, dynamic display, and photoelectric devices.
