Enhanced electrochemical and electrocatalytic activity of a new supramolecular manganese-porphyrin species containing four bis(bipyridine)(aqua)ruthenium(II) complexes

Electrocatalysis on tetraruthenated nickel and cobalt porphyrins electrostatic assembled films

“…By coordinating transition metal complexes to the periphery of the metalloporphyrin ring, one can enhance or introduce new catalytic and electrocatalytic properties. In fact, new multielectronic catalysts and electrocatalysts have been obtained, exploiting the electrochemistry and the electronic effects promoted by the peripheral complexes [30][31][32][33]. In addition, the nature, charge and spatial positioning of the peripheral groups can also be used to command the interaction with other molecular species and with themselves, generating molecular nanomaterials, such as the electrostatic assembled films of cationic tetraruthenated porphyrins (M-TRPyP) with anionic tetrasulphonated phthalocyanines (TSPc) [1,34,35].…”

Synthesis, spectroscopic and electrochemical investigations of supramolecular nickel(II)tetraazaporphyrin complexes

“…They offer a wide synthetic choice for creating varied molecular architectures and are being used as building blocks for the construction of artificial systems and catalysts for a verity of substrates [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The metalloporphyrins/ tetraazaporphyrins and ruthenium(II) polypyridyls are versatile and robust chromophores possessing strong visible region absorption and reversible redox behavior.…”

Supramolecular assemblies for electron transfer

“…Closely related is the following observation: electrocatalytic activity of a central manganese porphyrin (MnP) complex surrounded by four peripheral ruthenium-bipyridine ([Ru(bpy) 2 (py)(H 2 O)] 2+ ) complexes was demonstrated in the case of nitrite ion oxidation [43].…”
