The field of Supramolecular chemistry has reached a high level of sophistication and maturity, especially in the last 5-10 years. The sophistication is primarily evident in the highly complex chemical architectures that have been synthesized to accomplish specific functions such as selective binding and transport of substrates, in catalysis, and for the formation of assemblies, to name just a few of the applications. Many other molecular structures have been synthesized to form unusual materials with interesting and/or useful properties. From this point of view, the field is mature, as would...
