中文摘要：

手性是自然界的普遍现象，有关超分子手性的研究由于超分子体系中分子间非共价相互作用的可调性逐渐引起了人们的研究兴趣。本文综述了手性光学开关研究的最新进展，介绍了如何设计分子体系，由手性分子制备手性光学开关；基于超分子思想，介绍了由非手性分子参与形成的手性光学开关，并最终制备出完全由非手性分子组装得到的手性光学开关。

英文摘要：

Chirality can be observed on various levels in nature and the research related to supramolecular chirality has been received increasing interest due to the tunability of the non-covalent intermolecular interactions in supramolecular systems. The recent progress in the studies of chiroptical switch is reviewed. Chiroptical switch could be fabricated not only by chiral molecules, but also by the combination of chiral and achiral molecules. In some particular cases, chiroptical switch exclusively from achiral molecules has been realized.
