A glassy carbon electrode modified by a triply-fused-like Co(ii) polyporphine and its ability for sulphite oxidation and detection

Abstract

An original Co(ii) porphyrin conductive polymer is electrosynthesized which efficiently catalyzes sulphite oxidation in water offering opportunities for sensor development.

Recent Advances in Heterocyclic Nanographenes and Other Polycyclic Heteroaromatic Compounds

“…The intermediate magnesium(II) polyporphine 353.2a could be transmetalated to the corresponding cobalt(II) species 353.2b , 659 which was electrochemically converted into the fused polymer 353.3b . 660 In comparison to 353.2b , 353.3b was found to be more stable toward potential cycling in an aqueous matrix, and was thus employed for sensing of sulfite in aqueous solutions. Structurally related polymeric porphyrin tapes were also obtained by using oxidative chemical vapor deposition (oCVD) 661 − 666 and were utilized in photocatalysis 667 and ammonia sensing.…”

Recent advances in electrochemical meso- and β-functionalization of porphyrins and electrografting of diazonium porphyrins

“…When the backward potential or the applied potential was low (<0.40 V vs Ag/Ag + ), a semiconducting material was obtained (pMgP-I), where the MgP unit was kept intact inside the polymer with the probable formation of only one single meso-meso bond between each Scheme 1. Electrochemical oxidative C-C coupling between tri-meso-arylporphyrins (A, [10,11]) and Mg(II) porphine (B, [12,13,[15][16][17][18][19][20][21][22][23]). monomer unit.…”

“…The first applications of these promising metalated materials concerned sulphite detection [23] and O2 reduction reaction [22].…”

Tuning of interfacial charge transport in polyporphine/phthalocyanine heterojunctions by molecular geometry control for an efficient gas sensor

“…Until now, only MgP was used as a starting monomer for polyporphines synthesis, which is mainly ascribed to its relatively facile synthesis method, its good solubility in organic solvents and sufficiently low oxidation potential [33,34]. Although, zinc(II) and cobalt(II) polyporphine films were obtained recently by some of us but these were achieved by the ion replacement of Mg(II) in the polymeric film [35][36][37].…”
