Novel multiresponsive microgels based on poly(N-isopropylacrylamide) were synthesized to contain triphenylmethane leucohydroxide, and used to construct etalons. The optical properties of the resultant etalons were investigated, and their response to ultraviolet and visible irradiation, solution pH changes, and the presence of a mimic of the nerve agent Tabun characterized. We clearly show that the optical properties of the device depended dramatically on these stimuli. This investigation illustrates the versatility of the microgel-based etalon structure, and showcases the clear utility of such devices for remote actuation, color tunable optics, sensing, and potential remotely triggered drug delivery applications.
基于聚（N-异丙基丙烯酰胺）的新型多响应微凝胶被合成以包含三苯甲烷隐色碱，并用于构建光楔。研究了所得光楔的光学性质，并研究了它们对紫外线和可见光辐射、溶液 pH 值变化以及模拟神经毒剂沙林的存在的响应。我们清楚地表明，该器件的光学性质取决于这些刺激。该研究说明了基于微凝胶的光楔结构的多功能性，并展示了此类设备在远程驱动、可调谐光学、传感以及潜在的远程触发药物输送应用方面的明显优势。
