Abstract Luminescent responsive heterostructures with region‐domained emission and integrated responsiveness exhibit great potential in information security, but always suffer from the direct exposure of fingerprint at initial state, making it easy to decode hidden confidential information. Herein, first monochromatic hydrogen‐bonded organic framework (HOF) are reported based on VIA‐group‐based hybridization toward fully‐covert photonic barcodes. Designed HOF blocks different VIA‐group elements via a configuration‐assimilation‐based assembly method generate intrinsic heterostructures. Differentiated electronegativity endows each block distinct bonding stability, which triggers actions same stimuli, finally forming multicolor mode state. These can effectively hide information, further demonstrates coding capability as high‐security anti‐counterfeiting labels. findings offer novel insight exploitation smart‐responsive hetero‐HOF systems for advanced encryption anticounterfeiting applications.
