Enhanced Anion Transport Using Some Expanded Porphyrins as Carriers.
Abstract
Supramolecular chemistry involves the association of two or more chemical species through intermolecular interactions. The two components of a supermolecule have been named receptor and substrate, respectively. The receptor either natural or synthetic, is usually a large molecule that is able to bind a smaller chemical species. The substrate is the specie whose binding is being sought. It can be neutral as well as charged, such as a metal or an organic cation or an inorganic or organic anion. The geometry of both the initial, uncomplexed receptor and the final receptor-substrate complex can be spherical, tetrahedral, and/or linear. The receptor is said to be capable of effecting molecular recognition when it is able to bind, by virtue of its design, a specific substrate or set of substrates. Recognition is also the key first step that allows certain molecular receptors to serve as catalysts and/or carriers.
