Here we demonstrate facile synthesis method for formation of highly ordered mesoporous cubic Im–3 m titania thin film. The mesostructural ordering is strongly dependent on the aging condition after the spin-coating. The aging condition under low temperature and low humidity is found as an optimum co...
