Hydrogen Bonding in Supramolecular Functions

Abstract

Here are described some newer aspects, in relation to supramolecular function developments, of host-guest complexation based on multipoint hydrogen-bonding interactions in apolar organic media. The following topics are covered. A supramolecular strategy for the functional-structure construction provides a very simple route to a great variety of face-to-face porphyrin-quinone architectures. A supramolecular strategy for the structure elucidation presents an exciton-chirality-induction method for the assignments of absolute stereochemistry of chiral molecules. A supramolecular strategy for the three-dimensional encapsulation leads to versatile polar-guest binding via a polar microsolvation effect Some future prospects of supramolecular chemistry are also briefly referred to. These include (1) supramolecular control of organic solid and crystal structures by using divergent functional groups and (2) supramolecular complexation of polar guests in aqueous media as a result of balanced cooperation of polar and apolar interactions.KeywordsMolecular RecognitionSupramolecular ChemistryPhotoinduced Electron TransferChiral MoleculePolar CoreThese keywords were added by machine and not by the authors.
