Аннотация:N-methyl-2-pyrrolidone-soluble ferrocene-containing polychalcones, whichare promising as a platform for the formation of ferromagnetic coatings afterpyrolysis in an inert atmosphere is synthesized through the polycondensationof isophthalic aldehyde and 1,10-diacetylferrocene by the Claisen–Schmidtreaction. The structure and the molecular weight distribution of the polychal-cones is characterized by NMR, IR spectroscopy, and size exclusion chroma-tography. It is shown that the formation of polychalcones is accompanied bychain branching via the Michael reactions and the aldol-croton condensation.The structure of the linear fragments of the polychalcone chains is simulatedwith a tailored low-molecular model compound, that is 1,3-bis(3-ferrocenyl-1-propen-2-one)benzene, which is characterized by the NMR and IR spectros-copy as well as the X-ray diffraction analysis. The obtained results indicate anincreasing tendency for polychalcone chain branching with the temperaturegrowth during the Claisen–Schmidt reaction. The weight loss and the increasein magnetization under the conditions of pyrolysis of polychalcones at differ-ent temperatures is studied. The assumptions regarding the possible mecha-nisms of thermal destruction of ferrocene-containing macromolecules are putforward.
