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＝0.160n_C＋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.
