Coordination-driven self-assembly via the directional-bonding approach utilizes rigid transition metal acceptors and electron-rich donors to allow for complex, nanoscale 2D polygons and 3D polyhedra to be prepared under mild conditions and in high yields. To ensure proper rigidity and directionality, many acceptor and donor precursors contain largely carbon-rich aromatic and/or acetylenic moieties. This article introduces self-assembly as an alternative means of synthesizing carbon-rich materials and discusses the development, design, synthesis, and applications of carbon-rich supramolecular metallacycles and metallacages as well as the self-assembly of new diastereomeric carbon-rich supramolecular triangles.
通过定向键合方法进行的配位驱动自组装利用刚性过渡金属受体和富电子供体，使得能够在温和条件下高产率地制备复杂的纳米级二维多边形和三维多面体。为确保适当的刚性和方向性，许多受体和供体前体主要包含富含碳的芳香族和/或炔属部分。本文介绍了自组装作为合成富碳材料的一种替代方法，并讨论了富碳超分子金属环和金属笼的发展、设计、合成及应用，以及新型非对映体富碳超分子三角形的自组装。
