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.
