ENSEMBLE DE SELS MÉTALLIQUES DISSEMBLABLES QUI EST UN DENDRIMÈRE AYANT QUATRE TYPES OU PLUS DE COMPOSÉS DE SELS MÉTALLIQUES DISSEMBLABLES INTÉGRÉS DE MANIÈRE PRÉCISE EN SON SEIN, ET PROCÉDÉ DE PRODUCTION DE PARTICULES MÉTALLIQUES DE TAILLE SOUS-NANOMÉTRIQUE

摘要

Provided are a multiple-metal salt assembly of dendrimer in which multiple-metal salt compounds with a number of, for example four or more types, particularly five or more types of multiple metals can be assembled for each of parts with different environments so that, particularly, the total metal atom number becomes less than 60, a method for producing the same, and a method for producing subnano metal particles including the multiple-metal salt assembly of the dendrimer.Four or more types of multiple-metal salt compounds with multiple metal species are assembled for each of parts with different environments of dendrimer whose core is a group expressed by a following Formula (I):[Chem. 1]        -(X)_nC(Ph)_4-n-     (I)(in which n number of Xs independently represent a divalent group corresponding to a residue of a six-membered ring aromatic heterocyclic compound including, as a hetero atom, at least one selected from nitrogen, phosphorus, and arsenic, a derivative thereof, or a benzene derivative including an electron-donating functional group, Ph represents a phenylene group, and n represents an integer of 1 to 3).
