Abstract
The 3-hydroxy group of one glucopyranosinic ring of gamma-cyclodextrin was selectively substituted with an amino moiety to obtain a new compound able to complex copper(II). Indeed, the new ligand, an altro-gamma-CD, forms stable complexes with Cu(II), as the analogous 3-amino derivative P-CD previously exploited for the chiral separation of some amino acids by ligand exchange mechanism in capillary electrophoresis. Furthermore, the ligand forms a stable inclusion complex with anthraquinone-2-sulfonate. (C) 2008 Elsevier Ltd.
