Responsive luminescent materials that reversibly
react to external stimuli have emerged as prospective platforms for
information encryption applications. Despite brilliant achieve-
ments, the existing fluorescent materials usually have low
information density and experience inevitable information loss
when subjected to mechanical damage. Here, inspired by the
hierarchical nanostructure of fluorescent proteins in jellyfish, we
propose a self-healable, photoresponsive luminescent elastomer
based on dynamic interface-anchored borate nanoassemblies for
smart dual-model encryption. The rigid cyclodextrin molecule
restricts the movement of the guest fluorescent molecules, enabling
long room-temperature phosphorescence (0.37 s) and excitation
wavelength-responsive fluorescence. The building of reversible
interfacial bonding between nanoassemblies and polymer matrix together with their nanoconfinement effect endows the
nanocomposites with excellent mechanical performances (tensile strength of 15.8 MPa) and superior mechanical and functional
recovery capacities after damage. Such supramolecular nanoassemblies with dynamic nanoconfinement and interfaces enable
simultaneous material functionalization and self-healing, paving the way for the development of advanced functional materials.
