Abstract:
A hydrogen-bonded three-dimensional porous metal-organic framework [Mg(H2PCD)2(H2O)2]·2H2O (denoted as Mg-MOF·2H2O; H3PCD = 9-(2-(ethoxy(hydroxy)phosphonyl)ethyl)-9H-carbazole-3,6-dicarboxylic acid) was synthesized by the reactions of H3PCD and Mg(II) under solvothermal conditions. The free carboxylate group was maintained in the pore surface by adjusting the acidic reaction conditions. The highly stable Mg-MOF exhibits excellent performance for lead(II) sensing and removal from aqueous solutions.
