Title:
METAL-ORGANIC FRAMEWORK
Document Type and Number:
WIPO Patent Application WO/2023/176919
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an MOF having excellent heat resistance. The metal-organic framework has a structure SM-x which is composed of: an organic ligand; a structure Sx consisting of at least one among O2-, OH2, OH-, OCH3
-, and OC2H5
-; and metal ions, and in which two or more metal ions are bonded to one oxygen atom of the structure Sx, wherein two or more metal ions are present in the unit cell, and the water absorption A as determined by equation (1) is 25% or more. (1): Water absorption A=(W1-W2)/W2 (In the equation, W1 represents the mass of the metal-organic framework after being left alone until the equilibrium water content is reached under the conditions of a temperature of 25°C and a relative humidity of 50%, and W2 represents the mass of the mass W1-determined metal-organic framework after being left alone at a temperature of 200°C for 1 hour.)
