Abstract
The 1,1'-ferrocenediyldichlorosilane 1 was introduced into oxide matrices (SiO 2 , TiO 2 , Al 2 O 3 ) by non-hydrolytic sol-gel route. In all cases some degradation of the ferrocenyl moiety occurred. The materials were immobilized onto an electrode surface as a composite film with PTFE and their cyclic voltammograms were studied. For each sample a reduction wave around -375 mV was evidenced which was attributed to the reduction of [Fe III Cl x ] 3-x species arising from the decomposition of ferrocenyl species during the condensation process.
