Mi. Bazanov et al., ELECTROCHEMICAL STUDIES OF COBALT-CONTAINING PHTHALOCYANINE COMPOUNDS, Russian journal of electrochemistry, 34(8), 1998, pp. 818-821
Electrochemical properties of cobalt complexes of tetra-4-bromo-tetra-
5-nitro-, tetra-4-chlorotetra-5-nitro-, tetra-4-nitro-, and tetra-4-br
omo-substituted phthalocyanines are studied. The ligand electroreducib
ility in these compounds and optical properties of complexes are shown
to depend on the nature of substituents.
