The present invention provides a metal-organic framework which can both adsorb water vapor in low relative humidity and reduce the magnitude of the humidity difference between the adsorption humidity and the desorption humidity. A metal organic framework wherein the metal ion is an aluminum ion, a first ligand is an organic compound ion consisting of a first heterocycle having two carboxyl groups, and a heteroatom composing the first heterocycle is present on the minor angle side of the angle created by the two carboxyl groups, a second ligand is different than the first ligand, is an organic compound ion consisting of a second heterocycle having two carboxyl groups, and a heteroatom composing the second heterocycle is present on the major angle side of the angle create by the two carboxyl groups, and a third ligand is different than the first ligand and the second ligand, is an organic compound ion having two carboxyl groups, and the first ligand, second ligand, and third ligand are present in a specific ratio.

Organometallic framework

[OBJECT] To provide a metal-organic framework having high hygroscopicity under low humidity conditions, and a method for producing such a metal-organic framework. [SOLVING MEANS] A method for producing a coordinatively unsaturated metal-organic framework includes the steps of providing a precursor metal-organic framework comprising a metal cluster and a polycarboxylic acid ion and a monocarboxylic acid ion coordinated to the metal cluster, and allowing the precursor metal-organic framework and a metal salt having a Lewis acidity to coexist in a solvent to desorb at least a part of the monocarboxylic acid ion, which is coordinated to the metal cluster, from the metal cluster, as well as a coordinatively unsaturated metal-organic framework, including an MO(OH)-type metal cluster and carboxylic acid ions including a polycarboxylic acid ion as a polydentate ligand and a Cmonocarboxylic acid ion as a monodentate ligand coordinated to the metal cluster.

Provided is a method for manufacturing a porous body by which a porous body having a plurality of layers different from each other in pore diameter can be manufactured more easily than before. The method includes heating a raw material solution including a metal ion and an organic ligand to synthesize an interpenetrated metal-organic framework layer; and after synthesizing the interpenetrated metal-organic framework layer, synthesizing a non-interpenetrated metal-organic framework layer under conditions in which concentrations of the metal ion and the organic ligand in the raw material solution and/or a heat temperature are lower than that in synthesizing the interpenetrated metal-organic framework, to obtain a porous body including the interpenetrated metal-organic framework layer and the non-interpenetrated metal-organic framework layer stacked together.

Provided is a method for manufacturing a porous body by which a porous body including a plurality of layers different from each other in pore diameter may be manufactured by a fewer steps than before. The method includes: synthesizing a mixture of a non-interpenetrated metal-organic framework and an interpenetrated metal-organic framework; and obtaining a porous body including a stack of a non-interpenetrated metal-organic framework layer and an interpenetrated metal-organic framework layer from the mixture synthesized in the synthesizing, via a process of separating the non-interpenetrated metal-organic framework and the interpenetrated metal-organic framework from each other by utilizing density differences.

A housing for a member disposed at a vehicle exterior is formed by assembling a plurality of parts substantially in a vehicle longitudinal direction. At a matching portion when the plurality of parts are assembled together substantially in the vehicle longitudinal direction, a housing outer side end portion of a matching surface substantially at a vehicle frontward side is displaced further outward than a housing outer side end portion of a matching surface substantially at a vehicle rearward side. Or, the housing outer side end portion of the matching surface substantially at the vehicle rearward side may have a curved surface or a flat surface.
