Inclusion Complex of Gd(III) with β-Cyclodextrin and L-Tryptophan

Abstract

An inclusion complex of gadolinium(III) with L-tryptophan (Trp) and β-cyclodextrin (β-CD) with the composition Gd(Trp)3Cl3∙3β-CD∙nH2O was synthesized. It was established that the complex is formed due to the entry of the aromatic part of the L-Trp molecule into the β-CD cavity, and the Gd3+ ions are located in the outer sphere.
