COMPLEXATION OF METAL-IONS BY CYCLODEXTRINS

Organic ligand containing coordination metal ion complexes and the organometallic compounds in which the metal atoms are covalently bound can form regular inclusion complexes with cyclodextrins. Organic ligands for complexation of the metal ions may be also appropriate substituent groups of a chemically modified cyclodextrin. With non‐derivatised cyclodextrins only so‐called Outer Sphere Hydroxo‐complexes are formed. Metallocenes, arenes, rotaxanes, rhodium‐ and platinum‐complexes are the typical metal ion or atom containing guest molecules. These complexes can be utilised as catalysts, enzyme models, siderophores, colour and fluorescence enhancing reagents, drugs, etc. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
