油胺广泛应用于纳米材料和金属卤化物钙钛矿的合成。市售油胺试剂中的杂质进行了鉴定，纯化程序进行了解释，氯化铅/油胺混合物的有益效果进行了记录，并对材料合成的影响进行了讨论。发现0.12摩尔分数PbCl 2、PbBr 2和PbI 2在纯化、干燥和过滤的油胺中的悬浮液在加热至100 ℃时形成澄清溶液。给出了油胺和一种常见反式杂质的红外、拉曼和核磁共振光谱。
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 degrees C. The infrared, Raman, and NMR spectra of oleylamine and a common trans impurity present in literature reference IR spectra are presented.
