Reactive Silver and Cobalt Nanoparticles Modified with Fatty Acid Ligands Functionalized by Imidazole Derivatives

Abstract: Novel nucleophilic ligands were synthesized from oleic acid conjugated with 2-mercaptoimidazole via a UV-initiated thiol−ene reaction, and by a condensation of trans-9,10-epoxystearic acid with 4(5)-imidazoledithiocarboxylic acid. Nanoparticles (NPs) with 10−100 nm Ag(0) or Co(0) cores were obtained by reduction of Ag+ or Co2+ by borohydride in N,N-dimethylformamide or aqueous solutions respectively. The NPs capped with oleic acid or 9,10-epoxystearic acids were further covalently bound to 2-mercaptoimidazole … Show more

“…Thus, thermolysis of carboxylate metal complex with no use of solvent, stabilizer, or reducing agent should be conducted at high temperatures (~250 °C) since too low temperature leads to a stabilization shell composed of silver ions rather than the fully reduced silver atoms (Shim et al 2008; Szczęsny and Szłyk 2013). Other methods require the use of solvent, stabilizer, or reducing agent and thus the post-reaction cleaning procedures connected with removing by-products (Bromberg et al 2010; Rao and Trivedi 2005). …”
