Boronate assemblies characterized

Beyond the coordinative interactions described, boronate ester formation by itself has been shown to facilitate the generation of macromolecular and polymeric structures. Taking advantage of the covalent yet reversible nature of boronate ester formation has allowed for the formation of thermodynamically stable assemblies. Of course, simple monoesters, diesters, and triesters have been readily synthesized and characterized. Numerous reports have taken advantage of the formation of cyclic diesters as a means to define selectivity for molecular sensors, but these small cycles will not be discussed here. Attempts to synthesize and characterize macrocyclic, polymeric and extended covalently...
