Mechano-Programmable Circularly Polarized Luminescent Elastomers for Dynamic Information Encryption and Chiral Logic Gates

-hydroxyethyl methacrylate) matrix. The resulting elastomer simultaneously achieves efficient mechanophore activation, a robust chiral environment, and excellent mechanical compatibility (breaking strength ≈ 18 MPa, breaking strain ≈ 450%). It exhibits force-dependent, in situ, continuous, and reversible CPL responses. By further incorporation of a benzothiadiazole (BTz) green fluorophore, multicolor CPL outputs spanning green, orange, and red are realized under a single mechanical stimulus. Leveraging this programmable multidimensional optical behavior, we demonstrate mechanically triggered dynamic information encryption with hierarchical authentication and multi-input chiral logic gates. This work establishes a versatile platform for next-generation intelligent anticounterfeiting materials with in situ, mechano-regulated, and multiband CPL capabilities.
