Smart fluorescent patterns enable dynamic color variation under external stimuli, showing a much higher security level in the field of anti‐counterfeiting. However, there is still lacking of a simple and convenient way to achieve dynamic fluorescence changes. Herein, a fluorescent organohydrogel made up of a poly(N,N‐dimethylacrylamide‐co‐isopropylacrylamide) (p(DMA‐NIPAM)) hydrogel network and a...
Fluorescent patterns showing the unique color change in response to external stimuli are of considerable interest for their applications in anti‐counterfeiting. However, there is still a lack of intelligent fluorescent patterns with high‐security levels, presenting a dynamic display of encrypted information. In this study, a fluorescent organohydrogel is fabricated through a two‐step interpenetrating...
