abstract
Metal-organic frameworks (MOF) and UMOFs based on porous materials based on phosphonate ligands are discussed. Rubibao Fu and co-workers presented a series of divalent phosphonates using C 4, the compound was found to possess a series of interconnected 1D inorganic chains creating 1D channels that contain both water molecules and protonated phosphonate groups. Mao and co-workers prepared mixed-ligand La and Nd phosphonate/sulfonates utilizing N,NO-piperazinebis(methylenephosphonic acid) and para-sulfonylphenylphosphonic acid. Taddei and co-workers in Italy have recently reported two zirconium compounds with N,NO-piperazinebis(methylenephosphonic acid), which exhibits 1D channels that can reversibly desorb and sorb water molecules. Dines et al. reported Zr(O 3PC 12H 8PO 3) compound that showed a wide distribution of pore sizes.
