METAL-ORGANIC FRAMEWORK WITH CARBOXYLIC ACID ION HAVING TERPHENYL SKELETON AS LIGAND
An object of the present invention is to provide a novel metal-organic framework with a dicarboxylic acid having a terphenyl skeleton as an organic ligand and a gas storage method using such a metal-organic framework. A metal-organic framework comprising a carboxylate ion of formula (I) and a multivalent metal ion bonded to each other. (In formula (I), R.sup.1 and R.sup.2 each independently are a hydroxy group or an unsubstituted or substituted C1-6 alkyl group. R.sup.10 and R.sup.11 each independently are an unsubstituted or substituted C1-6 alkyl group. R.sup.20 is an unsubstituted or substituted C1-6 alkyl group. Provided that, as substituents on R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.10, R.sup.11, and R.sup.20, a carboxy group (COOH) and a carboxylate ion group (COO—) are excluded. In addition, R.sup.10 and R.sup.11 are not a methyl group at the same time.)
