A series of condensation polymers (polyesters and polyamides) of ferrocene and siloxane derivatives have been synthesized and characterized. Thus, 1,1′-di(chlorocarbonyl)ferrocene (CAFc) and four different siloxane derivativess1,3-bis(aminopropyl)tetramethyldisiloxane) (AP 0 ), R,ω-bis(3-aminopropyl)oligodimethylsiloxane (AP), 1,3-bis(hydroxypropyl)tetramethyldisiloxane (HP 0 ), and 1,3-bis(p-hydroxyphenyleneazomethine-3-propyl)tetramethyldisiloxane (HBS 0 )swere used as monomers for this purpose. A model polyamide was prepared by polycondensation of oxalyl chloride with AP 0 . This was analyzed as such or doped with ferrocene in order to appreciate the influence of the ferrocene units by comparison with the corresponding copolymer containing chemically linked ferrocene in the main chain. Thermal, mesomorphic, viscometric, and solubility behaviors of the obtained compounds were studied. Molecular masses were estimated by GPC. The polymers were investigated by cyclic voltammetry and UV-vis absorption spectroscopy in order to evaluate the redox properties and photochemical behavior.

New polyazomethines have been synthesized by the reaction between 2,5‐dihydroxy‐1,4‐benzoquinone and siloxane diamines differing by the siloxane sequence length. A dimer has also been prepared as a model compound. The products were characterized by spectral (FTIR and 1H‐NMR) and elemental analyses, GPC, viscosity measurements, solubility tests, and transmission electron microscopy (TEM). The different properties have been investigated by adequate techniques: thermal (DSC and TGA), spectral (UV–vis and fluorescence spectroscopy), redox (Differential Pulse Voltammetry). pH‐sensitivity and metal complexing ability were also evaluated. © 2008 Wiley Periodicals, Inc.
