Research Of Ferrenium Derivatives-POM Hybrid Materials

In this thesis, novel organic-POM hybrid materials were synthesized by reactions of ferrocenium derivatives and Keggin structure molybdophosphoric acid in solid state. All hybrid materials were characterized.The results were as follows:1. The hybrid materials' configuration is [Fc-R]3HPMo12O40 which was characterized by elemental analysis, ICP-AES, AAS and TG. The results of IR,XRD and XPS spectra indicated that the Keggin of heteropoly acid remain unchanged in the hybrid materials.2. The charge-transfer in the hybrid materials was existed by UV-vis and ESR. They suggested that the anion was reduced and formed charge-transfer hybrid materials.3. The prominent character of hybrid materials is the ferromagnet. And the results from Magnetic measurement show that the saturation magnetization strength is enhancing with the increase of the organic conjugation dimension. This can help to devise ferromagnetic molecular materials. In addition, the conductivity and electrochemical properties measurement show excellentoxidation-reduction properties and weak semiconductor behavior.The results indicated that hybrid materials can be used as ferromagnetic materials.
