Abstract Chiral sensing is essential in pharmaceuticals, food safety, and environmental monitoring, but effectively accurately detecting various enantiomers continues to be a substantial challenge. Inspired by the dynamic conformational change of olfactory receptor proteins, natural L‐carnosine (Car) used as ligand assemble first highly crystalline oriented chiral peptide‐based metal‐organic framework (MOF) thin films with liquid‐phase epitaxial layer‐by‐layer approach (named surfac‐coordinated MOF films, SURMOFs). By adjusting solvent environment, these at same time porous SURMOFs mimic flexibility exhibiting structural changes. This “breathing effect” enables ZnCar selectively sense six fragrance enantiomers, including (+)/(−)‐carvone, (+)/(−)‐menthol, (+)/(−)‐limonene. incorporating into quartz crystal microbalance (QCM) analyzing frequency shifts using convolutional neural networks (CNN), sensitive gravimetric biomimetic sensor capable multiple has been developed. With sensitivity range 10 200 ppm, reached recognition accuracy 98.58% for showcasing outstanding selectivity flexibility.
