Water-soluble silver nanoparticles stabilized by amino acid-derived N-heterocyclic carbenes: synthesis, properties and theoretical study of the nucleation process
{{output}}
Silver nanoparticles stabilized by amino acid-derived N-heterocyclic carbenes, denoted as Ag(NHCR)-NPs (R = H, 3a; Me, 3b; iPr, 3c; and iBu, 3d), were synthesized by reducing the parent complexes Na3[Ag(NHCR)2] (2a-d) with NaBH4 under appropriate reaction cond... ...
