The introduction of cationic surfactant DODA as counterions of [Eu(H₂O)₂SiW₁₁O₃₉]^5- can form a mesoscopic supramolecular assembly of (DODA)₄H[Eu(H₂O)₂SiW₁₁O₃₉], which aggregates into vesicles in chloroform. This POM-based vesicle can be further transferred into three-dimensional microporous architectures under moist air. The present methodology shows that, by combining inorganic chemistry and colloidal surface chemistry, a sequential self-assembling approach based on a series of linkable preorganized building blocks allows access to the fabrication of technological applicably POM-based microsized patterns, alternated with the soft lithographic method.
