Summary:Chiroptical switches, whose chiral optical signals such as optical rotatory dispersion (ORD), circular dichroism (CD) and circularly polarized luminescence (CPL) are reversibly interchangeable between two states, offer many promising applications in the fields of chiral sensing, optical displays, information storage, asymmetric catalysis and so on. Through various non-covalent interactions, supramolecular chiroptical switches have been constructed by combining the chiral and responsive functional components. This review summarizes the recent progress in the construction of supramolecular chiroptical switchable systems that reversibly respond to various stimuli, such as light, electricity, magnetic fields, mechanical force, solvents, pH, temperature, and chemical additives. The switching of supramolecular chirality in the forms of on/off, amplification/weakening and chirality inversion is shown. Additionally, the design of chiroptical switchable systems for chiral logic gates, data communication, chiral separation and asymmetric catalysis has been demonstrated. Future challenges in developing supramolecular chiroptical switches are also discussed. Recent progress in chiroptical switches including on/off, amplification, and inversion of the chiral signals such as ECD and CPL in supramolecular assemblies is shown.
Bibliography:Li Zhang received her PhD degree in physical chemistry from the Institute of Chemistry, Chinese Academy of Sciences (2004) under the supervision of Prof. Minghua Liu. Following graduation, she worked for 2 years at Tohoku University as a Postdoc fellow. She is currently an associate professor at the Institute of Chemistry, Chinese Academy of Sciences. She has carried out research into chiral supramolecular assemblies and chiroptical switches.
Shuai Li received his BS degree in Chemistry from Shandong University in China (2015) and MSc degree in physical chemistry from the Institute of Chemistry of the Chinese Academy of Sciences (2018) under the supervision of Prof. Minghua Liu. He focused on the research of supramolecular chirality regulation. He is currently pursuing a PhD degree at Duke University, USA.
Minghua Liu received his BSc from Nanjing University in 1986 and PhD from Saitama University, Japan, in 1994. After carrying out postdoctoral research at the institute of Physical and Chemical Research (RIKEN) and at the Tokyo University of Agriculture and Industry, he joined the Institute of Photographic Chemistry in 1998 and then the Institute of Chemistry, CAS in 1999, and has been working as a professor to date. His research interests cover supramolecular chemistry, colloid and interface science, self-assembly, and gel-based soft nanomaterials. He is particularly interested in chirality issues with regard to supramolecular and self-assembly systems.
Han-Xiao Wang received her PhD degree in organic chemistry under the supervision of Chuan-Feng Chen from the Institute of Chemistry, Chinese Academy of Sciences, in 2017. Her PhD research mainly focused on constructing orientational (pseudo)rotaxanes. After that she joined Professor Minghua Liu's Group as a postdoctoral fellow. She is currently an assistant professor at the Institute of Chemistry, CAS. Her current research interest lies in the design of chiral gelators and fine control over morphology and supramolecular chirality of their assemblies.
