Metal organic framework

Abstract

A metal organic framework, comprising: an organic ligand; a structure Sx constituted by one or more of O2-, OH2, OH−, OCH3−, and OC2H5−; and a metal ion, wherein the metal organic framework has a structure SM-x, in the structure SM-x, two or more metal ions are bonded to one oxygen atom in the structure Sx, the number of the metal ions in a unit lattice is two or more, and a water absorption rate A obtained by formula (1) is 25% or more: water ⁢ absorption ⁢ rate ⁢ A = ( W 1 - W 2 ) / W 2 ( 1 ) in the formula, W1 represents a mass of the metal organic framework after being left until an equilibrium moisture content is reached under conditions of a temperature of 25° C. and a relative humidity of 50%, and W2 represents a mass of the organic metal framework after obtaining the mass W1 and being left at a temperature of 200° C. for 1 hour.
