Nanoparticles serving as a multifunctional and multiaddressable dopant to modify the properties of liquid crystalline matrices are developed by combining cobalt ferrite nanocrystals with organic ligands featuring a robust photosensitive unit and a source of chirality from the natural pool. These nanoparticles provide a stable nanocomposite when dispersed in achiral liquid crystals, giving rise to chiral supramolecular structures that can respond to UV-light illumination, and, at the same time, the formed nanocomposite possesses strong magnetic response. We report on a nanocomposite that shows three additional functionalities (chirality and responsiveness to UV light and magnetic field) upon the introduction of a single dopant into achiral liquid crystals.
通过将钴铁氧体纳米晶体与具有强大光敏单元和天然来源手性的有机配体相结合，开发出了用作多功能和多可寻址掺杂剂以改变液晶基质性质的纳米颗粒。这些纳米颗粒分散在非手性液晶中时可提供稳定的纳米复合材料，产生可响应紫外光照射的手性超分子结构，同时，形成的纳米复合材料具有强磁响应。我们报道了一种纳米复合材料，在向非手性液晶中引入单一掺杂剂后，该材料展现出三种额外功能（手性以及对紫外光和磁场的响应性）。
