Strain‐Responsive Circularly Polarized Luminescence in Cholesteric Liquid Crystal Elastomers through Laser‐Engineered Microstructures (Adv. Funct. Mater. 30/2026)

Cholesteric Liquid Crystal Elastomers This cover features a porous cholesteric liquid crystal elastomer (CLCE) engineered with a femtosecond laser and coated with quantum dots. Under mechanical stress, the material exhibits a vivid, sensitive dual-color response. This interplay between the CLCE's structural color and quantum dots' photoluminescence creates a strikingly visual strain-sensing system, offering potential in advanced anti-counterfeiting applications.
