用一种简便快速方法合成了一系列长链有机胺插层V2O5化合物. 用粉末X射线衍射(XRD)、红外光谱(FT-IR)、漫反射紫外-可见光谱(DR UV-VIS)等手段对插层产品的结构进行了表征. 除了正十六胺插层V2O5产品外, 其它长链烷胺插层V2O5产品的层间距d001与长链烷胺碳数n之间具有良好的线性关系: d001＝0.160nC＋0.731 nm. 正十六胺与V2O5反应后生成两个插层相, 一个相的层间距d001为4.01 nm, 另一相的d001为3.20 nm. 此外, 研究了手性钛的螯合物Ti[(OC2H4)3N][OCH(CH3)2] (记为TEAIP)在V2O5层间的插层行为, 得到相应的插层产品.

A series of long-chain n-alkylamine-intercalated layered V2O5 materials were synthesized through a simple and quick route. X-ray diffraction (XRD), framework FT-IR and diffuse reflectance UV-visible spectroscopy (DR UV-Vis) were employed to investigate the structure of the obtained products. An excellent linear relationship between the basal interlayer distances of the n-alkylamine-intercalated V2O5 and the number of carbon atoms in the n-alkyl chain (d001＝0.160nC＋0.731 nm) with an exception for n-hexadecanamine was presented. n-Hexadecanamine-intercalated V2O5 was composed of two guest-intercalated layered phases, and the basal interlayer distances (d001) of the two phases were 4.01 and 3.20 nm, respectively. The intercalation behavior of titanium(IV) (triethanolaminato)-isopropoxide (TEAIP) in layered V2O5 was also investigated, and the TEAIP intercalated layered V2O5 product was obtained.
