The luminescent hydrogen‐bonded organic framework (HOF) based films have become one of the most remarkable materials for optical application, thus, developing facile synthesis methods and establishing multifunctional applications for HOF‐based luminescent materials are essential. Herein, a dual‐emitting Eu 3+ ‐functionalized HOF hydrogel film ( 1 ) is fabricated successfully. 1 emits a blue‐green long afterglow when turning off the UV lamp, and the long afterglow lifetime gets to 1.99 s. 1 performs great selectivity, high sensitivity, and low detection limit toward ofloxacin and flumequine, and the sensing toward ofloxacin and flumequine is in accord with the chroma and ratio modes. The fluorescent response mechanisms of 1 toward ofloxacin and flumequine are investigated in depth, which are further utilized to build an anticounterfeiting platform with high‐level security. The film‐based anticounterfeiting platform can conduct information encryption on demand inline with different fluorescent responses and can also fetch specific information by controlling the long afterglow intensity and excited light. This study not only provides a representative case of the fabrication of dual‐emitting Eu 3+ ‐functionalized HOF‐based hydrogel film but also opens the possibility of HOF‐based film as intelligent luminescent materials with multifunctionalities.
