Abstract

Abstract : 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 information decryption and transmission capacities, which are of great importance to achieve high‐level data protection security. Herein, robust aggregation‐induced emissive polymeric hydrogels with thermo‐triggered multistate fluorescence switching, shape memory, and self‐healing properties based on supramolecular dynamic lanthanide coordination interactions are presented. By a collective action of these promising properties, a fluorescent hydrogel‐based 3D information encoding platform is demonstrated for on‐demand information decryption, in which information pre‐encrypted in 3D hydrogel structures is stepwise decrypted by the control of external stimuli. Such unique on‐demand information decryption features are further expanded to the transmission of manifold customized messages to multiple receivers. Herein, the possibility of utilizing 3D fluorescent hydrogel structures for high‐level information encryption and on‐demand decryption is opened up. Abstract : Multifunctional aggregation‐induced emissive polymeric hydrogels are reported via lanthanide coordination, which is characterized with the desirable multistate fluorescence response upon temperature change. These promising advantages are favorable for programming materials into an advanced fluorescent hydrogel‐based 3D anticouterfeiting platform that allows high‐level encryption and on‐demand decryption of information, as well as simultaneous information transmission to multiple receivers.
