Abstract

The binding properties of the calix[4]arene-based artificial receptor (1) toward carboxylate-containing sugars in DMSO are demonstrated. The receptor shows the 1:1 host-guest complexation with the sugars. The hydrogen bonds forming to the hydroxyl groups play a crucial role for the guest selection.
