摘要： Despite the fact that the amount and type of gas to be stored may vary in accordance with the type of substituent, metal-organic frameworks only using a terephthalic acid having substituents within the limited range have been produced conventionally. An object of the present invention is to provide a novel metal-organic framework using a 2,5-disubstituted terephthalic acid. A metal-organic framework comprising a carboxylate ion of formula (I) and a multivalent metal ion bound to each other is a novel metal-organic framework, enabling a gas such as hydrogen and nitrogen to be store efficiently. (wherein in formula (I),
X is an unsubstituted or substituted cycloalkyl group, an unsubstituted or substituted aryl group, an unsubstituted or substituted heterocyclyl group or -Si(R 1 )(R 2 )(R 3 ) ; and Y is a single bond, an alkylene group, -O-, -S-, -S(O)-, - SO 2 -, -N(R 4 )- or a group formed by a combination thereof; provided that X-Y- is a phenyl group, a benzyloxy group, a pyrazol-1-yl group or a group of formula (II) except for a case where m is 3, 6, 8, 9, 10, 11 and 12).-

摘要： The object of the present invention addresses a problem of providing a novel hydrogen storage material containing a metal-organic framework that can effectively store hydrogen. Hydrogen can be effectively stored by use of a hydrogen storage material containing a metal-organic framework, the metal-organic framework comprising a carboxylate ion of formula (I) and a multivalent metal ion, wherein the carboxylate ion and the multivalent metal ion are bound to each other. (In formula (I), X is an unsubstituted or substituted C2-C20 alkyl group, an unsubstituted or substituted alkenyl group, an unsubstituted or substituted alkynyl group, an unsubstituted or substituted alkoxy group, an unsubstituted or substituted alkenyloxy group, an unsubstituted or substituted alkynyloxy group, a benzyloxy group, an unsubstituted or substituted alkylsulfanyl group, an unsubstituted or substituted alkenylsulfanyl group, an unsubstituted or substituted alkynylsulfanyl group, an unsubstituted or substituted alkylamino group, an unsubstituted or substituted dialkylamino group, an unsubstituted or substituted alkenylamino group, an unsubstituted or substituted dialkenylamino group, an unsubstituted or substituted alkynylamino group, an unsubstituted or substituted dialkynylamino group, a phenyl group, a sulfanyl group or an unsubstituted or substituted alkoxycarbonyl group.)

摘要： An object of the present invention is to provide a metal-organic framework capable of adsorbing a gas such as a hydrogen molecule or carbon dioxide at a practical level. The metal-organic framework is used for adsorbing a gas such as hydrogen or carbon dioxide and comprises a multivalent metal ion and a carboxylate ion of formula [I] [wherein in formula [I], X 1 to X 3 each independently represent a functional group of formula [II] (wherein in formula [II], Z is a single bond or a multivalent linking group, k is an integer of 1 to 4, and * is the position at which a bond is formed with a benzene ring) ; and Y 1 and Y 2 each independently represent a hydrogen atom, a halogeno group, a C1-6 alkyl group or the like, provided that when the multivalent metal ion is a trivalent metal ion, Y 1 and Y 2 each independently represent a halogeno group, a C1-6 alkyl group or the like], wherein the carboxylate ion and the multivalent metal ion are bound to each other.
