随着使用双光子聚合的直接激光写入的出现，高分辨率三维微结构的产生急剧增加。然而，开发刺激响应性光致抗蚀剂以产生四维（4D）微结构仍然是一个挑战。在此，我们提出了一种超分子液晶光子光刻胶的制作4D光子微致动器，如柱，花，蝴蝶，与亚微米分辨率。这些微米大小的特征显示了由湿度或温度变化引发的结构颜色和形状变化。这些发现为高分辨率4D光子微执行器的设计和创建提供了路线图。
With the advent of direct laser writing using two-photon polymerization, the generation of high-resolution three-dimensional microstructures has increased dramatically. However, the development of stimuli-responsive photoresists to create four-dimensional (4D) microstructures remains a challenge. Herein, we present a supramolecular cholesteric liquid crystalline photonic photoresist for the fabrication of 4D photonic microactuators, such as pillars, flowers, and butterflies, with submicron resolution. These micron-sized features display structural color and shape changes triggered by a variation of humidity or temperature. These findings serve as a roadmap for the design and creation of high-resolution 4D photonic microactuators.
