Résumé     
Via the procedure of oxidative coupling of furan monomers using either titanium tetrachloride (TiCl4) or ferric chloride (FeCl3) as oxidants, two different compounds are obtained. Different experimental analyses including infrared, Raman, optical absorption and ESR techniques are combined and completed by density functional theory to differentiate between both resulting compounds. It is found that both oxidants induce cleavage of aromatic rings. The rates of the resulting aliphatic sequences in each compound are different. Then, to elucidate the effect of oxidant on the electronic properties of the resulting compounds, an ESR dependant temperature study is done. We show that the compound obtained by using FeCl3 contains ionic structure. The effect of temperature on the dynamics of these electronic species is also studied. (C) 2011 Elsevier B.V.
