Claim:
1. A composite having a core-shell structure in which a core is covered by a shell, wherein the core comprises a metal nanoparticle, the shell comprises a porous coordination polymer (PCP), and the PCP is formed of a metal ion and an organic ligand, wherein the PCP forms layers that cover the metal nanoparticle, wherein the PCP has an average thickness extending from a surface of the composite to the metal nanoparticle of 1 to 200 nm, wherein the metal nanoparticle comprises a noble metal nanoparticle, and wherein the organic ligand forming the PCP is selected from the group consisting of (a) a compound in which two, three, or four carboxyl groups are bonded to an aromatic ring selected from the group consisting of benzene, naphthalene, anthracene, phenanthrene, fluorene, indane, indene, pyrene, 1,4-dihydronaphthalene, tetralin, biphenylene, triphenylene, acenaphthylene, and acenaphthene, wherein the ligand is optionally mono-, di-, or trisubstituted by a substituent selected from the group consisting of halogen atoms, a nitro group, an amino group, an acylamino group, a cyano group, a hydroxyl group, methylenedioxy, ethylenedioxy, a linear or branched alkoxy group having 1 to 4 carbon atoms, a linear or branched alkyl group having 1 to 4 carbon atoms, SH, a trifluoromethyl group, a sulfonic acid group, a carbamoyl group, an alkylamino group, and a dialkylamino group, (b) an unsaturated divalent carboxylic acid, and (c) a nitrogen-containing aromatic compound that coordinates through two or more ring nitrogen atoms, wherein the compound is optionally mono-, di-, or trisubstituted by the substituent.
