  • Porous coordination polymer and application therefor
    Patent number: 9670127
    Abstract: An object of the present invention is to provide a novel porous coordination polymer having superhydrophobicity. The present invention relates to a porous coordination polymer comprising: a divalent or trivalent metal ion; and an organic ligand represented by the following formula (1): wherein X1, X2, and X3 are the same or different, and each represent CO2?, CS2?, PO32?, PO42?, AsO32?, AsO42?, SO3?, SO4?, SeO3?, SeO4?, TeO3?, or TeO4?; and R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, and R12 are the same or different, and each represent hydrogen or C1-20 alkyl; the metal ion and the organic ligand being alternately linked by a coordinate bond.
