New Polymer Syntheses Part 57: Thermally Stable New Ferrocene-Polyazomethines, Synthetic Methodology, and Characterization

A new interesting category of higher thermally stable polyazomethines containing ferrocene in the polymers main chain6a–e was synthesized by solution-polycondensation reaction of 1-(m-formylphenyl)-1′-(5-formyl-2-methoxyphenyl)-ferrocene monomer4with different aliphatic and aromatic diamines. A model compound5was synthesized from dialdehyde monomer4with aniline and was characterized by elemental and spectral analyses. The desirable resulting polymers were characterized by elemental and spectral analyses, in addition to solubility measurement using different solvents. The thermal properties of these polymers were evaluated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) measurements. The redox behaviours were studied for the ferrocene polymers in comparison with both the parent ferrocene monomer and the model compound by using cyclic voltammetry (CV).
