Combination of chelating behaviour with molecular recognition as interaction for ligand exchange chromatography

Abstract

A novel chelating resin was synthesized, composed of chemically bonded glycinocyclodextrin (S-CD-G) to which silica gel was added as matrix and silanes with amino groups as spacer. It showed efficient complexation with transition metal cations. In this report the copper and zinc resin complexes were investigated for application as stationary phases for the separation of substituted phenol isomers. The results revealed that the copper resin complex has a high potential for this application.
