Anodic oxidation and physicochemical properties of various porphyrin-fluorenes or -spirobifluorenes: Synthesis of new polymers for heterogeneous catalytic reactions

New conducting polymers were obtained by anodic oxidation of various unmetallated or metalloporphyrins bearing fluorene or 9,9′-spirobifluorene groups in meso positions. The anodic behaviour of monomers and polymers is presented. The physicochemical properties (IR, UV–Vis spectroscopy and spectroelectrochemistry, scanning electron microscopy, electronic microanalysis) of these new materials are then discussed.
