Stoichiometric Control of Multiple Different Tectons in Coordination-Driven Self-Assembly: Preparation of Fused Metallacyclic Polygons

摘要

In the bottom-up strategy of materials self-assembly, it is essential to be able to control the shapes and sizes of supramolecules at the nanoscale precisely and easily. Over the past two decades, many finite supramolecular two-dimensional (2D) and three-dimensional (3D) structures with well-defined and often predetermined shapes, sizes, and geometries have been prepared via coordination-driven self-assembly of simple building blocks. With the general success and breadth of the coordination-driven approach, some attention has turned toward optimization rather than the discovery of new materials. However, it is often the search for and discovery of new materials that lends considerable insight into their formation and opens the door to many new compounds.
