A novel, simple, and efficient route for preparing MoO 3 , V 2 O 5 , and WO 3 films has been developed from layered polyoxometallate (POM)‐alkylamine hybrid films by calcination. The highly ordered hybrid films were self‐assembly deposited in a one‐step process using clear precursor POM solutions, prepared by reacting layered MoO 3 , V 2 O 5 , and WO 3 ·H 2 O powders with hexylamine in the presence of water. The morphology of the resulting films can be tuned by removing the intercalated hexylamine molecules from the as‐prepared hybrid films through UV irradiation before calcination.
