Telechelic or side-functionalized diorganosiloxanes with ferrocenylimine groups

► New telechelic or side-functionalized oligodiorganosiloxanes with aminopropyl groups were prepared. ► Aminopropyl groups attached to the siloxane were converted in ferrocenylimine ones. ► Iron spin state, electrochemical behavior and solvent effect were investigated by 57Fe Mossbauer spectroscopy, cyclic voltammetry, and UV-Vis absorption spectroscopy, respectively.
