Three-Dimensional Solvent-Vapor Map Generated by Supramolecular Metal-Complex Entrapment

摘要

Supramolecular assemblies have become increasingly popular over the past few years, especially in areas such as catalysis, gas sequestration, and separation. Similarly, interesting approaches for the detection of toxic gases and vapors of volatile organic compounds (VOCs) have been studied to develop an artificial nose that is capable of identifying these species in an unambiguous and simple way. The use of supramolecular and crystalline arrays of metal complexes with electronic transitions that are sensitive to the presence of a variety of volatile molecules, has received considerable attention. However, although metal complexes of platinum, gold, palladium, and copper have been widely employed for vapor detection, rhenium has been rarely used. Herein, we propose to use a zeolite framework for the supramolecular assembly of rhenium complexes with applications to vapor sensing.
