| Abstract: | Dawson-type molybdovanadophosphate was synthesized and then used for fabricating organic-inorganic multilayer films with a generation-4 poly(amidoamine) dendrimer as an organic spacer on electrode substrate.The multilayer films were characterized by XPS,UV-Vis,CV and AFM.The results show that the multilayer films grow gradually and uniformly,and four redox processes are observed in CV,the formal potentials of the composite films are shifted linearly to negative position at higher pH.The multilayer films ele... |
