Programming Multistate Aggregation?Induced Emissive Polymeric Hydrogel into 3D Structures for On?Demand Information Decryption and Transmission

Fluorescent hydrogels have recently become one of the most prominent materials for smart confidential information protection. But it is still quite challenging to develop a 3D anticounterfeiting platform with on-demand decryption and transmission capacities, which are great importance achieve high-level data protection security. Herein, robust aggregation-induced emissive polymeric thermo-triggered multistate fluorescence switching, shape memory, self-healing properties based on supramolecular dynamic lanthanide coordination interactions presented. By collective action these promising properties, fluorescent hydrogel-based encoding demonstrated decryption, in pre-encrypted hydrogel structures stepwise decrypted by control external stimuli. Such unique features further expanded manifold customized messages multiple receivers. possibility utilizing encryption opened up.
