To provide a new way to fabricate novel wave-adsorbing material, ferrocenyl organic metal magnetic resin (FOMR) was successfully prepared from ferrocenyl bisphthalonitrile via an effective and mild solvent-thermal route. The structure analysis of as-synthesized FOMR was performed using Fourier transform infrared spectrophotometer and ultraviolet–visible absorption spectrum. Magnetic behavior of the sample were also studied by vibrating sample magnetometer and the experimental results indicated that the magnetic material were ferromagnetic with maximum saturation magnetization of 1.3 emu g− 1 at 300 K. Measurements of electromagnetic parameters of FOMR show that the maximum absorbing peak has a bandwidth of 7.0 GHz (RL < 4 dB). The specific gravity of FOMR was about 0.86. On the basis of these results, the novel magnetic materials are believed to have potential applications in the microwave absorbing area and in biomedical field.
