interaction-induced CD hydrogel possessing both self-healing behavior and good
stability can be a most attractive candidate in biomedical areas.
Host-guest binding affinity between β-CDs and azobenzenes has already been
investigated as 1:1 complex and widely used to fabricate smart supramolecular
hydrogels. When under UV light (365 nm) or visible light (400–500 nm),
