Reversible fluorescent adhesives based on covalent adaptable networks with dynamic AIE crosslinking: in situ visualization of adhesion capability.

A new family of reversible fluorescent adhesives based on Diels-Alder covalent adaptable networks with dynamic AIE crosslinks was developed. The accurate intrinsic correlation between the emission behavior, cross-linking state, and adhesion capability can be established, enabling the in situ visualization of adhesion capacity.
