A new supramolecular gel via host-guest complexation with cucurbit[8]uril and N-(4-diethylaminobenzyl)chitosan

► A novel supramolecular gel based on cucurbit[8]uril and N-(4-diethylaminobenzyl)chitosan was prepared. ► Cucurbit[8]uril acted as crosslinker and the host-guest interaction was the main driving force for the formation of the gel. ► This supramolecular gel system showed thermosensitive and pH-sensitive properties.
