Abstract:

Supramolecular photochemistry provides experimental tools and mechanistic concepts pertinent to the examination of the fate of Air Force chemicals and how they may be photochemically transformed into environmentally benign substances. This benefication process of converting AF chemicals to environmentally benign materials is termed mineralization. A biomemetic strategy is adopted for which the laboratory model of benefication is based on processes occurring in nature. This biomimetic model provided us with the strategy of employing supramolecular photochemical systems to achieve the mineralization of Air Force chemicals via photosensitized degradation. A host molecule the Air Force chemical is brought into sustainable contact with a host system humic acid, a metal oxide, a porous solid, etc. which initiates the mineralization process.
