Intercalation and polymerization of 4-anilinoaniline and 4-anilinoanilinium iodide in the VOPO4 and V2O5 interlayer spaces

Abstract

Reactions of 4-anilinoaniline and 4-anilinoanilinium iodide with powdered VOPO₄·2H₂O suspended in ethanol gave compounds intercalated with the 4-anilinoanilinium cation. Reactions of 4-anilinoaniline and its hydrogen iodide salt with powdered V₂O₅·nH₂O suspended in ethanol resulted in the direct oxidative polymerization of 4-anilinoanilinium moieties in the V₂O₅ Interlayer space. The polymerization processes of 4-anilinoaniline and its hydrogen iodide salt in the VOPO₄ and V₂O₅ Interlayer spaces are discussed on the basis of powder X-ray diffraction patterns, infrared and X-ray photoelectron spectroscopies as well as gel-permeation chromatography.
