Abstract
Four [(CdSe)13(RNH2)13] derivatives (R = n-propyl, n-pentyl, n-octyl, and oleyl) are prepared by reaction of Cd(OAc)2·2H2O and selenourea in the corresponding primary-amine solvent. Nanoclusters grow in spontaneously formed amine-bilayer templates and are characterized by elemental analysis, IR spectroscopy, UV-vis spectroscopy, TEM, and low-angle XRD. Derivative [(CdSe)13(n-propylamine)13] is isolated as a yellowish-white solid (MP 98 °C) on the gram scale. These compounds are the first derivatives of magic-size CdSe nanoclusters to be isolated in purity.
摘要
四种[(CdSe)13(RNH2)13]衍生物（R = 正丙基、正戊基、正辛基和油基）是通过 Cd(OAc)2·2H2O 和硒脲在相应的伯胺溶剂中的反应制备的。纳米团簇在自发形成的胺双层模板中生长，并通过元素分析、红外光谱、紫外-可见光谱、TEM 和低角度 XRD 进行表征。[(CdSe)13(n-丙基胺)13]衍生物以黄色白色固体（MP 98°C）的形式在克级规模上分离出来。这些化合物是首次分离出的纯度较高的魔法尺寸 CdSe 纳米团簇的衍生物。
