CARVALHO, M. Fernanda N.N.  e  FERNANDES, Tiago A.. Redox Properties of CU(I) Camphor Hydrazone Complexes. Port. Electrochim. Acta [online]. 2011, vol.29, n.5, pp.329-333. ISSN 0872-1904.  https://doi.org/10.4152/pea.201105329.

The electrochemical properties of the one-dimensional coordination polymers [{CuX}₂(YNC₁₀H₁₄O)]_n (X=Cl: Y=NMe2 1a, Y=NHMe 1b, Y=NH₂ 1c; X=Br: Y=NH₂ 2c) and dimers [{Cu(YNC₁₀H₁₄O)}₂(μ-X)₂] (X=Cl: Y=NMe2 3a; Y=NHMe 3b; X=Br: Y=NMe₂ 4a; Y=NHMe 4b) were studied by cyclic voltammetry (CV) and controlled potential electrolysis (CPE). All complexes display anodic and cathodic processes. The anodic processes involve the oxidation of the metal site (Cu(I)→Cu(II)), while the cathodic processes are based on the ligand. The substituent (Y) at the camphor hydrazones (YNC₁₀H₁₄O) plays a relevant role in the electrochemical properties and reactivity of Cu(I) coordination polymers and Cu(I) dimmers, as corroborated by CPE.
