A hydrazone-linked COF (DvDf-C3XJ-COF) with hydrogen-bond reinforcement and abundant coordination sites was synthesized, exhibiting strong fluorescence and high sensitivity/selectivity for Hg detection, with a detection limit of 1.65 × 10 M. The fluorescence quenching for Hg is attributed to coordination interactions, which occur through a dynamic quenching process.
