Incorporating stimuli-responsive mechanisms into chiral assemblies of nanostructures offers numerous opportunities to create optical materials capable of dynamically modulating their chiroptical properties. In this study, we demonstrate the formation of chiral superstructures by assembling Fe3O4@polyaniline hybrid nanorods by using a gradient magnetic field. The resulting superstructures exhibit a dual response to changes in both the magnetic field and solution pH, enabling dynamic regulation of the position, intensity, and sign of its circular dichroism peaks. Such responsiveness allows for convenient control over the optical rotatory dispersion properties of the assemblies, which are further integrated into the design of a chiroptical switch that can display various colors and patterns when illuminated with light of different wavelengths and polarization states. Finally, an optical information encryption system is constructed through the controlled assembly of the hybrid nanorods to showcase the potential opportunities for practical applications brought by the resulting responsive chiral superstructures.

用于信息加密的双响应 Fe3O4@聚苯胺手性超结构
将刺激响应机制纳入纳米结构的手性组装中,为创造能够动态调节其手性光学特性的光学材料提供了许多机会。在这项研究中,我们通过使用梯度磁场组装Fe 3 O 4 @聚苯胺杂化纳米棒来证明手性超结构的形成。由此产生的上层结构对磁场和溶液 pH 值的变化表现出双重响应,从而能够动态调节其圆二色性峰的位置、强度和符号。这种响应性允许方便地控制组件的旋光色散特性,这些特性进一步集成到手性光学开关的设计中,当用不同波长和偏振态的光照射时,该开关可以显示各种颜色和图案。最后,通过混合纳米棒的受控组装构建了光学信息加密系统,以展示由此产生的响应手性超结构带来的实际应用的潜在机会。
