Recognition of Anions Hardback
Edited by Ramon Vilar
Part of the Structure and Bonding series
A large number of biologically relevant species are negatively charged, the- fore it is not surprising that nature has developed sophisticated receptors to recognise, detect and transformanions.
For example, complex receptors such as phosphate- and sulphate-binding proteins are employed by living cells to selectively recognise these two geometrically analogous anions.
In addition to their roles in biological systems, some anions also have important en- ronmental impacts.
For example, cyanide, pertechnetate and chromates pose serious health problems if present in water supplies. Because of their important biological roles and potential environmental impact there is great current interest in developing molecular receptors to selectively recogniseanionsandindoingsobeabletosequester, transformor sense them.
The six chapters presented in this volume provide an overview of anion recognition and the most recent advances in this fast-growing area of supramolecular chemistry are highlighted.
