Exfoliation of Layered Oxovanadium Phosphate VOPO4·2H2O in Tetrahydrofuran through Intercalation of 4-Butylaniline

VOPO4 intercalated with 4-butylaniline was exfoliated in THF to form a homogeneous solution, thereby yielding delaminated sheets. The exfoliated oxide layers were reassembled into a thin film morphologically much differed from the intercalation compound.
