Abstract

The redox behavior was investigated by using cyclic voltammetry (solvent, WCN; room temperature). In all cases two pairs of waves were observed, and the two redox potentials were as follows: 4a,+ 0.64 and+ 1.35 V vs. Ag/AgCl; 4b,+ 0.38 and+ 1.22 V; 4c,+ 0.17 and+ 1.14 V. From the fact that the two peak currents in the oxidation side are almost equal and the dication'shows the cyclic voltammogram corresponding to the pair of waves in the ...
