発明の名称 (英語) Method for producing a three-dimensional structure
発明の概要(英語) The three-dimensional structure of the present invention is a three-dimensional structure formed on a base.
This three-dimensional structure contains a plurality of porphyrins, a plurality of first metal ions, and a plurality of specific organic molecules.
The porphyrin contains two or more functional groups.
The first metal ion is a metal ion for linking the functional group of one porphyrin to the functional group of another porphyrin.
The above specific organic molecule is an organic molecule that forms a coordinate bond with a metal ion contained in the two-dimensional structure and that has only one site to coordinate to the metal ion.
特許請求の範囲(英語) [claim1]
1. A method of producing a three-dimensional structure structure formed on a base, comprising stacked two-dimensional structures, comprising the steps of: (i) forming a two-dimensional structure on the surface of a liquid; (ii) depositing the two-dimensional structure on a base so that its in-plane direction is parallel to the surface of the base; (x) immersing the base on which the two-dimensional structure is deposited into a solvent; and (iii) repeating a cycle including the step (i)_the step (ii) and the step (x) once or more, wherein the two-dimensional structure contains a plurality of porphyrins, a plurality of first metal ions, and a plurality of specific organic molecules,
the porphyrin contains two or more carboxyl groups,
the first metal ion is a metal ion for linking the carboxyl group of one porphyrin to the carboxyl group of another porphyrin,
the specific organic molecule is an organic molecule that forms a coordinate bond with a metal ion contained in the two-dimensional structure and that has only one site to coordinate to the metal ion.
[claim2]
2. The production method according to claim 1, wherein the porphyrin is a porphyrin containing four carboxyl groups but not containing a central metal ion coordinated to a porphine ring, or is a porphyrin metal complex containing four carboxyl groups and a central metal ion coordinated to a porphine ring.
[claim3]
3. The production method according to claim 1, wherein
the first metal ion is divalent copper ion or divalent nickel ion, and
the specific organic molecule is a molecule containing a nitrogen-containing aromatic ring.
[claim4]
4. The production method according to claim 3, wherein the specific organic molecule is pyridine.
[claim5]
5. The production method according to claim 1, wherein the porphyrin is a porphyrin metal complex containing four carboxyl groups and a cobalt ion coordinated to a porphine ring.
[claim6]
6. The production method according to claim 1, wherein the porphyrins are cross-linked by dinuclear paddle wheel structures, each dinuclear paddle wheel structure being composed of four carboxyl groups and two first metal ions,
each side of each of the dinuclear paddle wheel structures is coordinated with one specific organic molecule,
the two-dimensional structures are linked by pi -pi interactions between the specific organic molecules coordinated to the sides of each of the dinuclear paddle structures, and
the specific organic molecule contains a pi electron.
[claim7]
7. The production method according to claim 1, wherein the step (i) is a step of forming the two-dimensional structure on the surface of the liquid by adding a second solution containing the porphyrins and the specific organic molecules to a first solution containing the first metal ions.
[claim8]
8. The production method according to claim 1, wherein the step (ii) is a step of bringing the base closer to the two-dimensional structure, with the surface of the base kept parallel to the surface of the liquid, and thereby depositing the two-dimensional structure on the base.
