In this paper, according to the synthesis idea of "point, line and plane", we got three types of ferrocenyldrazone ligands by combining the integrated ferrocenyl groups and the usions hydrazone groups with chemical synthesis. The N and O atoms in the hydrazone groups which have unique coordination characteristics were used to react with the transition metal ion to form metal complex. The structures, the morphologies and the dielectric properties have been investigated. The main researches are as follows:1.The organic polymer magnetic materials, dielectric property of materials and the recent developments of the hydrazone complexes were introduced in this paper.2.The chemical synthesis methods of the ferrocenylhydrazone and the metal coordination complex (Fc-M) were investigated. And the structure and micro morphology of those compounds were analysed by the ultimate analysis, GPS, IR, TGA, XRD and SEM to confirm the coordination modes, thermal stabilities, crystallization characteristics and the shape of the particles.3.The changing characteristics of the dielectric constant(ε) and the dielectric constant imaginary part(ε") with the changing of temperature and the frequency (0.1~18GHz) were discussed. The magnetic parameters of Fc-M in the temperature of5K and300K, and the variations of magnetic conductivity(μ’),magnetic loss(μ") along with the changing frequency were investigated. 4.The applicable currect situation of the composites (JH1, JH2, JH3) which be used as the mobile phone antenna and the microstrip antenna substrate medium were introduced. Then the three kinds of composite materials (JH1, JH2, JH3) were compared with the general polymer resin ABS in the antenna gain, antenna benefit, RL and the materials compatibility to get the potential application advantages of the JH1,JH2,JH3.5.The characteristic of change of the molecular structure, thermal stability, crystal and microcosmic morphology of the Fc-M complexes after the radiation processing by the60Coγ high-energy ray was investigated by the IR, TGA, XRD and SEM. The cause of the change of the dielectric and magnetic was explained in the view of structure change.6.The chemical reactions of terephthalic ferrocenylhydrazone polycondensation (Fc-DB) with different copper salts were investigated, which were occurred in the same solvent, reaction temperature and reaction time. The composition, thermal stability,.crystallization and microstructure of the reaction products were discussed. The dielectric constant(ε’), the dielectric constant imaginary part(ε") and their changing characteristics of with the frequency (0.1~18GHz) of the reaction products were also e studied.7.The composition, structure and microstructure of the pyrolysis products were investigated, which come from oxalic ferroceylhydrazone polycondensation metal complexes (Fc-CS-M) and NTC ferroceylhydrazone polycondensation metal complexes (Fc-ASYS-M) at high temperature (400℃,800℃and1200℃). The dielectric and magnetic properties of Fc-CS-M pyrolysis products also were studied.
