Functionalization of Polymer-Wrapped Silver Nanoclusters and Potential Applications as Antimicrobial Mask Materials.

ABSTRACT: The poly(methacrylic acid) (PMAA) polymer stabilized silver nanoclusters Ag_n (n = 2-9), synthesized in aqueous solution by the selected light wavelength irradiation photolysis approach, have been functionalized with thiol and amine ligands and successfully transferred from aqueous to organic media. Low- or high-resolution positive mass spectra showed constant species composites with the molecular formula Ag_nL_n-1 [n = 2 to ∼9, L = butylmercaptan (C₄H₉S), thiolphenol (C₆H₅S), or dodecanethiol (C₁₂H₂₅S)] and proved that the molecules consist of deprotonated sulfur ligands in each species with one positive charge.
