Over the past few decades, supramolecular chirality in discrete metallosupramolecular architectures has received considerable attention. In this review, a comprehensive summary of discrete, chiral coordination-driven structures, including helices, metallacycles, metallocages, etc., is presented. Although chirality can be introduced prior to, during or even after the coordination self-assembly process, this review puts major emphasis on the more recent development of metallosupramolecular architectures from chiral components, where chirality arises from the enantiopure or racemic scaffolds (bridging or auxiliary ligand). Special attention will be paid to homochiral metallo-assemblies using achiral components where chirality is obtained as a consequence of the twisting of the ligands. Additionally, the potential applications of homochiral metallosupramolecular architectures are also discussed. We hope that this review will be of interest to researchers attempting to design new elaborate homochiral metallosupramolecular architectures with even greater complexity and potential for functions such as chiral recognition, enantiomer separation, asymmetric catalysis, nonlinear sensors, and devices.
在过去的几十年中，离散金属超分子体系中的超分子手性受到了相当多的关注。在这篇综述中，全面总结了离散的、手性配位驱动的结构，包括螺旋、金属环、金属笼等。尽管手性可以在配位自组装过程之前、期间甚至之后引入，但本综述主要侧重于从手性配体出发的金属超分子结构的最新发展，其中手性源于对映纯或外消旋支架（桥联或辅助配体）。特别关注使用非手性配体获得手性的同手性金属组装体，其中手性是由于配体的扭曲而获得的。此外，还讨论了同手性金属超分子结构的潜在应用。我们希望这篇综述能引起研究人员的兴趣，他们试图设计具有更高复杂性和潜在功能的新型精致同手性金属超分子结构，例如手性识别、对映体分离、不对称催化、非线性传感器和器件。
