Electrochemical preparation and characterisation of Poly(Luminol–Aniline) films

Electroanalysis of ascorbic acid (vitamin C) using nano-ZnO/poly(luminol) hybrid film modified electrode

“…For comparison, ZnO-NPs/GCE and PLu/GCE were prepared and used for further investigation. to the oxidation of a primary amino group of luminol monomers [46][47][48][49][50][51]. Upon scan reversal a cathodic wave with a peak potential centered at 0.49 V (Pc 1 ) was observed.…”

“…The chemical composition of poly(luminol) film is possibly analogous to that of polyaniline (PANI). PANI has been confirmed to exist in the form of a sequence of benzene rings, alternating in reduced and oxidized segments, or as only oxidized dimeric segments [46][47][48][49][50][51]. The redox reaction of PLu is analogous to the fully redox form of polyaniline that is shown in Scheme 2.…”

Electrochemiluminescence Characterization of Poly(luminol‐benzidine) Composite Films and Their Analytical Application

“…Luminol contains an aromatic amino-group that should enable it to copolymerize with aniline [9,10]. Furthermore, benzidine could be electropolymerized to form polybenzidine film and copolymerize with other anilinic type monomers via the formation of À C À N ¼ C À and À C À NH À bonds [14,15].…”

“…The composite film of the polyluminol with Ni 2þ showed electrocatalytic effect on the electrooxidation of urea and presented better ECL analytical performances for urea [8]. Recently, Ferreira et al developed a new route for the preparation of self-doped polyanilines, where poly(luminolaniline) films were prepared on gold electrode surface by electrochemical copolymerization of luminol and aniline from acidic aqueous medium [9,10]. Their results show that the copolymerization extends the films electroactivity in solutions with pH 8 due to the presence of polyluminol in the composite films.…”

Chemiluminescence of 5-(azo-para-phenylene-N-aza-15-crown-5)-phthalhydrazide

“…14 Electro-chemiluminescence determinations have recently been reported using luminol or its chemical modifications such as deposition on gold 15,16 or silver nanoparticles, 17 on graphite-methacrylate 18 or glass-carbon composite electrodes 19 on platinum electrodes 20 or as a film formed by copolymerization with aniline. 21 Derivatives of luminol with azo-calixarenes 22 have also been reported to present weak FL and significant CL. Also phthalhydrazide-ionophores such as styrylphthalhydrazides with crown ethers 23 and aza-crowned isoluminol 24 were obtained.…”
