Advances in self-assembled ultrathin polyoxomolybdates multilayers

Abstract

The research on the assembly and function of organized molecular films has gained more and more interest. Electrostatic interactions can be employed to assemble polyoxomolybdates in surface confined multilayers. Ultrathin multilayer films of polyoxomolybdates and organic molecules by the self-assembly method have been reviewed. At the same time, self-assemblies in aqueous solution are also reported, such as wheel-shaped clusters (Mo₁₅₄), hollow spherical “blackberry”-like vesicles (Mo₇₂Fe₃₀) and Keggin structures. Polyoxomolybdate multilayers are promising candidates for diverse applications including electrocatalytic, photo- and electro-chromic systems. The development in this particular field of materials science may be highlighted in the future.

Key words： polyoxomolybdates; multilayer films; self-assembled
