摘要: Films of crown-ether substituted diphthalocyanine lutetium (CR-Pc2Lu) have been studied by cyclic voltammetry. In contact with K+ or Na+ aqueous electrolyte, two reversible one-electron steps lead to the formation orange cation CR-Pc2Lu+ and blue anion CR-Pc2Lu−. With other alkali metal cations, irreversibility both increases in order K+, ⪡ Li+ < Rb+, Cs+. In acid medium (HCl HClO4), voltammetry cannot be performed absence added simultaneously solution, destruction films occurs. a KCl + HCl KClO4 HClO4 disproportionation CR-Pc2 Lu proceeds two-electron voltammetric peak takes place steps. A E-pH “Pourbaix” diagram is established.
