An unprecedented acid/base stable Cu-based metal–organic framework with good catalytic activity for the reduction of 4-nitrophenol

• Constructing a new coordination polymer with semirigid and quadridentate flexible ligands.
• Complex 1 exhibits excellent endurance in acid/base aqueous solutions.
• Complex 1 has good catalytic activity for the reduction of 4-nitrophenol in NaBH4 solution.

A new 3D metal–organic framework with pcu topology {[Cu2(TPOM)(ddpa)2]}n (1) was synthesized under solvothermal condition by employing flexible tetrakis(4-pyridyloxymethylene) methane (TPOM) and semirigid 4,4′-dicarboxydiphenylamine (H2ddpa) as well as Cu(II) ion. Complex 1 exhibits good endurance in acid/base aqueous solutions and a high catalytic activity for the reduction of 4-nitrophenol in excess NaBH4 solution.

A new 3D metal–organic framework with pcu framework was synthesized by employing flexible tetrakis(4-pyridyloxymethylene)methane (TPOM) and semirigid 4,4′-dicarboxydiphenylamine (H2ddpa) as well as Cu(II) ion. In complex 1, TPOM shows a rare two coordinated mode. Complex 1 exhibits excellent endurance in acid/base aqueous solutions and a good catalytic activity for the reduction of 4-nitrophenol in excess NaBH4 solution.Figure optionsDownload as PowerPoint slide
