With the rapid development of information technology, encrypted storage is becoming increasingly important for human life. The luminescent materials with a color-changed response under physical or chemical stimuli are crucial coding and anticounterfeiting. However, traditional fluorescent usually face problems such as lack tunable fluorescence, insufficient surface-adaptive adhesion, strict synthesis conditions, hindering their practical applications. Herein, series lanthanide hybrid organogels (Ln-MOGs) were rapidly synthesized using simple method at room temperature through coordination between ions 2,6-pyridinedicarboxylic acid 5-aminoisophthalic acid. And multicolor inks also prepared based on Ln-MOG hyaluronic acid, advantages being easy to write, color-adjustable, water-responsive discoloration, which has been applied paper-based anticounterfeiting technology. Inspired by responsiveness water, we designed logic system that can realize single-input operations (NOT PASS1) double-input (NAND, AND, OR, NOR, XOR). encryption binary code be actualized utilizing different modes circuit system. By adjusting energy sensitization luminescence mechanism in gel structure, reading writing ability verified, great potential field pattern encryption.
