Jun Porcelain‐Like Birefringent Supramolecular Film for Multiple Logic Data Storage (Advanced Optical Materials 16/2025)

Multiple Logic Data Storage Supramolecular plastic film can be created with a pair of oppositely charged surfactant and polyelectrolyte through solid phase molecular self‐assembly. Upon stretching, the hydrophobic surfactant bilayers would yield unduplicable case‐dependent birefringence due to the difficulties of molecular arrangement in solid phases. This is in high analogue to ancient Chinese Jun porcelain, thus offers unduplicable anticounterfeiting technique. More details can be found in article 2403382 by Yun Yan and co‐workers.
