Porphyrinic zirconium-based MOF with exposed pyrrole Lewis base site as an efficient fluorescence sensing for Hg2+ ions, DMF small molecule, and adsorption of Hg2+ ions from water solution

Abstract The microporous zirconium-based MOF, as known [PCN-221], was successfully prepared by the solvothermal reaction method using meso-tetra(4-carboxyphenyl) porphyrin (TCPP) as a ligand and used as a fluorescent sensor for sensitive and selective recognition of Hg2+ ions, DMF small molecule, and adsorption of Hg2+ ions. The sensing of [PCN-221] showed a quenching response of Hg2+ ions with a fast fluorescent response rate under
