摘要: Abstract The synthesis of symmetrically tetra substituted metallophthalocyanines (MPcs) (M = Co, Zn, MnCl) bearing four 4‑methoxyphenylthiazole‑2‑thio‑units were reported. structures the newly synthesized molecules proposed according to elemental analysis, 1H NMR, FT-IR, and UV–vis spectral data. Redox active metal centers CoII; Cl-MnIII electropolymerizable substituents on peripheral positions Pc rings preferred for syntheses MPcs increase redox activity electrochemically polymerization ability complexes. properties characterized with voltammetry in situ spectroelectrochemistry techniques. Then, electropolymerized glassy carbon electrodes (GCE). Finally, GCE/MPc tested as electrochemical sensors detection ascorbic acid (AA), dopamine (DA) uric (UA) by using differential pulse (DPV) technique. Voltammetric analyses indicated that GCE/CoPc electrode selectively detected DA good sensitivity, while GCE/MnClPc GCE/ZnPc only UA. This work provided a simple easy approach modification selective sensitive AA, UA detections.
