The ability of the organic solvent <i>N</i>-methyl-2-pyrrolidone (NMP) as a suitable medium for application in star-like gold nanostructure (AuNS) synthesis with a tunable morphology at ambient conditions has been investigated. The time-dependent analysis of the UV-vis absorption spectra of Au^IIICl₄ ^- in a pure NMP solution illustrates the role of NMP as simultaneous complexing and reducing agents. Kinetic studies indicate that Au^IIICl₄ ^- in NMP solution is reduced to Au^ICl₂ <sup>-<ACS omega9484-9495https://www.ebi.ac.uk/biostudies/studies/S-EPMC8945176biostudies-literature<i>N</i>-Methyl-2-pyrrolidone as a Reaction Medium for Gold(III)-Ion Reduction and Star-like Gold Nanostructure Formation.PMC8945176Andrieu-Brunsen AMirdamadi Esfahani MGoerlitzer ESAEngstler JKunz UVogel Nfalse<i>N</i>-Methyl-2-pyrrolidone as a Reaction Medium for Gold(III)-Ion Reduction and Star-like Gold Nanostructure Formation.The efficiency of a wet chemical route to synthesize gold nanostructures with tunable size and shape significantly depends on the applied solvent and the interaction of solvent molecules with other species such as gold ions.
