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 Hg²⁺ detection, with a detection limit of 1.65 × 10⁻⁶ M. The fluorescence quenching for Hg²⁺ is attributed to coordination interactions, which occur through a dynamic quenching process.

用于 Hg2+ 荧光检测的腙连接共价有机框架


合成了具有氢键增强和丰富配位点的腙连接 COF （DvDf-C3XJ-COF），对 Hg²⁺ 检测表现出强荧光和高灵敏度/选择性，检出限为 1.65 × 10⁻⁶ M。Hg²⁺ 的荧光猝灭归因于配位相互作用，配位相互作用是通过动态猝灭过程发生的。
