摘要：

Dion-Jacobson phases are layer perovskites of the general formula A'[A(n-1)B(n)O(3n+1)], where A' is typically an exchangeable alkali or alkali earth ion. Because of their low layer charge density, acid-exchanged Dion-Jacobson phases are easily exfoliated to make single-sheet colloids. When the conditions temperature and pH were controlled, densely tiled monolayers of anionic sheets derived from HCa2Nb3O10, HSr2Nb3O10, HCaLaNb2TiO10, and HLaNb2O7 were grown on cationic substrates. Multilayer films were also assembled by alternately adsorbing these sheets and organic polycations.
