Estimating the term…
It is an object of the present invention to provide a storage material for a gas such as hydrogen, carbon dioxide, methane, or acetylene (excluding nitrogen gas) comprising a metal-organic framework comprising a hydroxamic acid group as a bonding site. A metal-organic framework comprising a multivalent metal ion and a molecule comprising an unsubstituted or substituted hydroxamic acid group and one or more sites capable of being bonded to the multivalent metal ion is contained. The molecule is preferably at least one compound selected from the group consisting of compounds of formulas (I) to (III).
A storage material for a gas other than nitrogen, comprising a metal-organic framework wherein a multivalent metal ion is bonded to a molecule comprising an unsubstituted or substituted hydroxamic acid group and one or more sites capable of being bonded to the multivalent metal ion.
A metal-organic framework wherein a multivalent metal ion is bonded to a molecule comprising an unsubstituted or substituted hydroxamic acid group and one or more sites capable of being bonded to the multivalent metal ion (provided that a metal-organic framework obtained by formation of a bond between Ti4+ or Zr4+ and benzene-1,4-dicarbohydroxamic acid is excluded).
