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).

Compounds, compositions, and method for modulating processes mediated by Retinoid X Receptors using retinoid-like compounds which have activity selective for members of the subclass of Retinoid X Receptors (RXRs), in preference to members of the subclass of Retinoic Acid Receptors (RARs). Examples of such compounds are bicyclic benzyl, pyridinyl, thiophene, furanyl, and pyrrole derivatives. The disclosed methods employ compounds for modulating processes selectively mediated by Retinoid X Receptors.

摘要:
Aromatische Dicarbonsäuren der Formel in der R¹, R², m, n und X die in der Beschreibung genannte Bedeutung haben, können aus den zugrunde liegenden Bisphenolen der Formel hergestellt werden, wenn man die Bisphenole zunächst zu den Bissulfonaten umsetzt, die Sulfonatgruppen katalytisch mit H₂ entfernt und die dabei erhaltenen Kohlenwasserstoffe in bekannter Weise zweifach acyliert und die Acylgruppen zu den Carboxylgruppen oxidiert. Viele der so herstellbaren aromatischen Dicarbonsäuren sind neu.

摘要:
Reactive polymeric compositions are prepared by subjecting arylcyclobutene monomeric compositions to polymerization conditions to provide a partially polymerized composition; and removing the partially polymerized composition from said conditions. The partially polymerized composition can be subsequently subjected to polymerization and curing conditions to provide a cured polymeric composition.
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.
