Abstract
Oleylamine is widely used in nanomaterial and metal-halide perovskite synthesis. Impurities in commercially available oleylamine reagents are identified, purification procedures are explained, beneficial effects on lead chloride/oleylamine mixtures are documented, and impacts on materials synthesis are discussed. Suspensions of 0.12 mole fraction PbCl2, PbBr2, and PbI2 in purified, dried, and filtered oleylamine were found to form clear solutions upon heating to 100 °C. The infrared, Raman, and NMR spectra of oleylamine and a common trans impurity present in literature reference IR spectra are presented.Keywords
