Abstract:
1. A method for producing a resin-supported platinum cluster complex comprising the steps of: (a) forming a platinum complex represented by the general formula (chemical formula 2) wherein R 1 comprises a carrier and a hydrophilic polymer chain, wherein the carrier is hydrophobic and the hydrophilic polymer chain is connected both to the carrier and to the NR 2 2 group and the molecular weight of R 1 is about 1,000 to 100,000, R 2 , may be identical or different, is a hydrogen atom, an alkyl group, an aryl group, and, however, NR 2 2 may form a pyridine ring, an acridine ring or a quinoline ring, X is a halogen atom, R 6 COO − , SO 4 − , CN − , NO 3 − or SCN − , wherein R 6 is an alkyl group or an aryl group, R 3 is an unsaturated hydrocarbon ligand, n is an integer from 0 to 3, from a nitrogen-containing compound represented by the general formula (chemical formula 1) wherein R 1 and R 2 are the same as defined above, and a platinum compound represented by the general formula wherein M is an alkali metal, an alkaline earth metal or a quaternary ammonium ion represented by N + R 5 4 , wherein R 5 , may be identical or different, is a hydrogen atom, an alkyl group or an aryl group, m is an integer indicating the electrical charge number of M, and X, R 3 and n are the same as defined above, and (b) allowing the platinum complex to react with a reducing agent to produce the resin-supported platinum cluster complex containing a platinum particle core with an average diameter of from 1 nm to 10 nm.
