Jun Porcelain‐Like Birefringent Supramolecular Film for Multiple Logic Data Storage

Abstract Information security is of predominant significance, while multiple logic information encryption techniques remain challenging. Here it is reported that upon coupling the unduplicable Jun Porcelain‐like birefringence and it enables polarized fluorescence with solid phase molecular self‐assembly(SPMSA), multiple logic information encryption can be achieved upon correctly applying UV light and polarizing angles. Since each birefringence is unique and can be transformed into a corresponding digital bar code, the multiple logic can be further encrypted with the assistance of a digital bar code bank, thus yielding the ultimate information security.
