Effect of tunable redox behavior of bis chelate substituted 1,10-phenantroline Cu(II) complexes on its reaction with superoxide anion in DMSO. Toward a simple criterion to identify a SOD-like mechanism

Tunable half wave potential (E1/2) Cu(II) complexes, were used to study the disproportion of O2
- − by the electrogenerated Cu(I)species in DMSO, as a quick guide test for a compound, before being proven in biological assays.194
