Title:
DISSIMILAR-METAL SALT ASSEMBLY WHICH IS DENDRIMER HAVING FOUR OR MORE TYPES OF DISSIMILAR-METAL SALT COMPOUNDS PRECISELY INTEGRATED THEREIN, AND PRODUCTION METHOD FOR SUBNANO METAL PARTICLES
Document Type and Number:
WIPO Patent Application WO/2018/159505
Kind Code:
A1
Abstract:
Provided are: a dissimilar-metal salt assembly which is a dendrimer capable of having a large number of, i.e., four or more types, particularly five or more types of dissimilar-metal salt compounds having dissimilar metals precisely integrated therein at respective sites with different environments, such that the total number of metal atoms is smaller than 60; a production method for the dissimilar-metal salt assembly; and a production method for subnano metal particles using the dissimilar-metal salt assembly which is a dendrimer. According to the present invention, four or more types of dissimilar-metal salt compounds having dissimilar metal species are integrated in respective sites with different environments in a dendrimer in which the core is a group represented by formula (I): (in the formula, n-number of X's each independently represent a 6-membered ring aromatic heterocyclic compound having, as a heteroatom, at least one selected from nitrogen, phosphorus, and arsenic, a derivative thereof, or a divalent group which is a residue of a benzene derivative having an electron-donating functional group, Ph represents a phenylene group, and n represents an integer of 1-3).
