Electrocatalytic properties of meso-tetraphenylporphyrin cobalt for nitric oxide oxidation in methanolic solution and in Nafion® film

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

“…Metalloporphyrins are highly interesting in analytical chemistry [1] and are therefore an exciting class of compounds which could be incorporated into polymeric films. Thus, immobilization of metalloporphyrin catalysts on electrode surfaces has been researched intensively and different methods have been used for this purpose: (i) simple adsorption of the porphyrin on various surfaces (silica [2,3], alumina, quartz [4], Highly Oriented Pyrolytic Graphite (HOPG) [5,6]); (ii) ion-exchange reaction on clay mineral, zeolite, layered dihydroxides [2]; (iii) immobilization of porphyrins in specific membranes (porous sol-gel films [7,8], PVC [9], Nafion Ò [10][11][12], polysiloxanes [13]); (iv) covalent binding of porphyrins on specific polymers (polymethacrylates [14,15], preformed specific polythiophene [16,17] or polypyrrole via an aryl thiol link [18]); (v) chemical polymerization of a monomer in which a polymerizable unit (thiophene) is linked to a porphyrin ring through a flexible chain [19]; (vi) immobilization of metalloporphyrins in electropolymerized films [20]. This last method has been extensively developed following different routes .…”

A Novel Supramolecular Assembly Film of Porphyrin Bound DNA: Characterization and Catalytic Behaviors Towards Nitric Oxide

“…Since Malinski and Taha [1] reported the application of an electropolymerized nickel porphyrin film electrode for the detection of NO, the metalloporphyrin biosensor has intensively been investigated for amperometric measurements of NO [2-8]. The methods for the immobilization of metalloporphyrins onto the electrode surface include electropolymerization of metalloporphyrins [2-3], doping with metalloporphyrins of polypyrrole film [4-5], and deposition of metalloporphyrins entrapped in Nafion film [6-8].…”

Nitric Oxide Detection with Glassy Carbon Electrodes Coated with Charge-different Polymer Films

“…A 2/3 of water-insoluble H 2 TPP has been found to distribute in hydrophilic ion channels and the other 1/3 in hydrophobic region of Nafion film [24]. If Fe(TPFPP) was distributed in hydrophilic region, it is surrounded by water molecules and may form hydroxo-complex, (HO - )Fe(III).…”
