Porphyrins are a kind of aromatic molecules possessing unique physic-chemical properties. In this manuscript, it was thus utilized to synthesize 5,10,15-tris(4-aminophenyl)-20-phenylporphyrin and cobalto(5,10,15-tris(4-aminophenyl)-20-phenylporphyrin). In addition, conducting cobalto(5,10,15-tris(4-aminophenyl)-20-phenylporphyrin) polymeric films were successfully prepared by electropolymerization approach on glassy carbon electrode in the presence of dimethyl formamide solution and 0.1 M tetra-n-butyl ammonium perchlorate at 100 mV/s scan rate. The synthesized polymeric films were evaluated as the active electrode materials to detect an antioxidant (Antipyrine) present in pharmaceuticals and the limit of detection is ~ 74 μM.
In the title indolin-2-one derivative, C(15)H(11)NO, the phenyl ring and the oxoindoline fused-ring system (r.m.s. deviation = 0.011 Å) are aligned at 48.52 (6)°. In the crystal, inversion-related mol-ecules form an N-H⋯O hydrogen-bonded dimer via an eight-membered {⋯HNCO}(2) synthon. The dimeric aggregates are linked into a three-dimensional architecture via C-H⋯O and π-π inter-actions between the five- and six-membered rings of the fused ring system, with an inter-centroid distance of 3.4538 (8) Å.
Diolefinic antibacterial laser dye namely 1,4-Bis[2-(4-Pyridyl) Vinyl] Benzene (4PVB)have been investigated electrochemically using cyclic voltammetry, chronoamperometry, convolution and deconvolution voltammetry combined with digital simulation techniques at a platinum electrode in 0.1 mol / L Tetra Butyl Ammonium Perchlorate (TBAP) in solvent 1,2-dichloroethane. The diolefinic species were reduced by consuming two sequential electrons to form radical anion and dianion. The second electron transfer was followed by chemical step i.e the electrode reaction proceed as EEC scheme. In scanning the potential to positive direction, the diolefinic laser dye compound was oxidized by loss of one electron, which was followed by a fast chemical process ( isomerization or association). The pathway of electrode reaction and the electrochemical parameters of the investigated compound were discussed & determined using cyclic voltammetry and chronoamperometry techniques. The extracted electrochemical parameters were verified and confirmed via digital simulation and convolutive voltammetry methods.
