Abstract

Programmable dual-mode (two- or three- dimension, 2D/3D)-coupling responsive coating constitutes one of the most promising strategies to ensure the security of anti-counterfeiting and information encryption, but it is still lack of effective approaches to integrate stimuli-responsive 2D and 3D information. Herein, we develop a self-growing method to achieve this purpose based on photoswitchable fluorescence and supramolecular interaction (dipole-dipole interaction) toward advanced multi-dimensional anti-counterfeiting and encryption. In our method, trifluoromethyl-rich monomers (2,2,2-trifluoroethyl methacrylate (TFEMA) and 2,2,3,4,4,4-hexafluorobutyl acrylate (HFBA)), polymerizable green fluorescent dye (2-(6-(dimethylamino)−1,3-dioxo- 1H-benzodeisoquinolin-2...
