报告内容:Molecular machines have undergone comprehensive investigation, leading to the reporting of various artificial molecular machines encompassing molecular motors, propellers, switches, and shuttles. Our focus lies in the development of supramolecular systems demonstrating molecular motion within crystals. Within a crystal lattice, molecules assume fixed positions, forming a directional and high-density array. The coordinated motion of individual molecules, facilitated by intermolecular interactions, induces diverse functionalities in crystals, such as polarity conversion and mass transport, resulting from the periodic nature of these crystals. In addition to a comprehensive introduction to dielectrics and molecular ferroelectrics, this talk will discuss recent progress in low-dimensional ferroelectrics and type I multiferroics based on supramolecular approaches.
