A multiple-metal salt assembly of a dendrimer in which multiple-metal salt compounds with a number of, for example, four or more types of multiple metals can be assembled for each of parts with different environments so that the total metal atom number becomes less than. Also, a method for producing the multiple-metal salt assembly, and a method for producing subnano metal particles including the multiple-metal salt assembly of the dendrimer.

Multiple metal salt assembly of dendrimer having four or more types of multiple-metal salt compound precisely assembled, and method for producing subnano metal particles

A method of producing a metal complex-supporting mesoporous material that can support a metal complex in the pores thereof without causing aggregation of the metal complex. A metal complex-supporting mesoporous material supporting a metal complex in the pores thereof without causing aggregation of the metal complex. A method of producing a mesoporous material supporting metal-containing nanoparticles using the metal complex supported in the pores of the mesoporous material as a template. A solution of a metal complex prepared by a phenyl azomethine dendrimer compound having a specific structure is brought into contact with a mesoporous material so that the metal complex of the phenyl azomethine dendrimer compound is supported by the mesoporous material.

A method for producing a substrate having dispersed particles of a dendrimer compound on the surface thereof, the method including: an application step including dissolving a phenyl azomethine dendrimer compound in a solvent to prepare a solution, and applying the solution on the surface of a substrate; and a volatilization step including volatilizing the solvent from the solution applied on the surface of the substrate, the phenyl azomethine dendrimer compound included in the solution having a concentration of no greater than 5 &#x3bc;mol/L is employed.

Method for producing substrate having dispersed particles of dendrimer compound on the surface thereof, and substrate having dispersed particles of dendrimer compound on the surface thereof

A method for preparing carbon nanotubes including attaching a catalyst consisting of a compound in which a transition metal element of Group 8, 9 or 10 is coordinated to a nitrogen-containing dendrimer compound having at least one nitrogen atom, to which a metal element may be coordinated, on a surface of a substrate, and thermally decomposing a carbon compound in the vicinity of the substrate while supplying the carbon compound on the surface of the substrate to which the catalyst is attached. The catalyst for producing the carbon nanotubes is a compound in which a transition metal element of Group 8, 9 or 10 is coordinated to a nitrogen-containing dendrimer compound having at least one nitrogen atom to which a metal element may be coordinated.
