Abstract

Tetrathiafulvalene (TTF) is readily and irreversibly intercalated by vanadium oxide xerogel (V2O5 1.6 H2O) in a mixed ethanol/water dispersion medium. The resulting material (TTFx V2O5 with x < 1.8) is an ill-organized, insoluble solid, which contains a large amount of strongly bound water molecules. An XPS analysis shows that an important fraction (up to ∼ 25% of the vanadium ions are in the V(IV) state. There is some indirect spectroscopic evidence that this material is a significantly better electronic conductor than the parent xerogel.
