NEW MAGNETIC NANOMATERIALS OF HYPERBRANCHED FERROCENE-CONTAINING POLYPHENYLENES PREPARED IN LIQUID AND SUPERCRITICAL CARBON DIOXIDE

In this work hyperbranched ferrocene-containing polyphenylenes have been synthesised for the first time by polycondensation of 1,1-diacetylferrocene in liquid and supercritical carbon dioxide as an environmentally friendly solvent. It was found that the incorporation of ferrocene units into polyconjugated system under mild temperatures proceeds without degradation of ferrocene elements. These polymers were found to be convenient precursors for preparation of a new type of magnetic materials that can be used in various devices.
