Metal organic framework, separation membrane, and method for producing metal organic framework

Abstract

The present invention provides a metal organic framework suitable for increasing a flux of a permeation fluid permeating through a separation membrane. The metal organic framework of the present invention includes a metal ion and an organic ligand. The organic ligand includes, besides a functional group to be coordinated with the metal ion, a first functional group and a second functional group different from the first functional group. The second functional group is a hydroxy group, a nitro group, or a carboxyl group. A ratio of the number of moles of the second functional group with respect to a total value of the number of moles of the first functional group and the number of moles of the second functional group is 30 mol % or less.
