Abstract

New magnetic nanomaterials based on soluble ferrocene-containing polyphenylenes were synthesized at 20–80 °C both under normal conditions and under ultrasonic irradiation. The maximum magnetization of nanomaterials containing magnetite nanoparticles was 15 G cm 3 g −1 in a magnetic field of 2.5 kOe. According to transmission electron microscopy, the average statistical sizes of magnetic nanoparticles were in the range of 12–19 nm.
