Synthesis and Characterization of Gold Nanoparticles with Surface Ligands Derived from a Primary Phosphine

Observation of uniform ligand environments and 31P–197Au coupling in phosphine-terminated Au nanoparticles

Phosphine-terminated gold nanoparticles exhibit unexpectedly uniform ligand environments that enable the identification of ³¹P–¹⁹⁷Au coupling for the first time in these systems.

Nanoporous ionic organic networks: stabilizing and supporting gold nanoparticles for catalysis

Nanoporous ionic organic networks (PIONs) with a high ionic density (three cation-anion pairs per unit) have been synthesized by a facile SN2 nucleophilic substitution reaction. Owing to the electrostatic and steric effect, those ionic networks with porous channels can stabilize and support gold (Au) nanoparticles (NPs) in 1-2 nm. The Au@PION hybrid materials used as a heterogeneous catalyst were highly active, selective, and stable in the aerobic oxidation of saturated alcohols.
