Description
Summary:[Display omitted] •Phosphonium polyelectrolytes act simultaneously, as reducing, and stabilizing agents for the gold nanoparticles.•Gold spherical particles with diameters in the range of 3–20 nm.•Gold nanoparticles can be dispersed in water, methanol and DMSO.•Higher molecular weight polymer-gold nanoparticles complexes exhibited better stability in the ambient conditions. The introduction of cationic groups onto the surface of gold nanoparticles (GNPs) is a valuable synthetic technique with many applications. This study reports the synthesis of the functionalization of GNPs with phosphonium groups presented in the ring opening metathesis (ROMP)-type polymer backbone. The formation of nanoparticles was revealed with UV-spectroscopy and Transmission Electron Microscopy (TEM). The presence of polyphosphonium ligand on the surface of the GNPs was confirmed by XPS and 31P NMR spectroscopy. Higher molecular weight polymer-GNPs exhibited better stability in the ambient conditions than the phosphonium polymers which possessed lower molecular weights. Phosphonium-based polymers can act, simultaneously, as reducing and stabilizing agents for the gold nanoparticles.
