The bottom-up synthesis of plasmonic NHC@CuNPs from common starting reagents, the formation of the synthetically accessible NHC-Cu(I)-Br complex and its reduction by NH·BH is reported. The resulting NHC@CuNPs have been characterized in detail by XPS, TEM and NMR spectroscopy. The stability of NHC@CuNPs was investigated under both inert and ambient conditions using UV-Vis analysis. While the NHC@CuNPs are stable under inert conditions for an extended period of time, the NPs oxidize under air to form CuO with concomitant release of the stabilizing NHC ligand.
