An expression has been derived for the concentration of oxidant and reductant at the surface of an expanding spherical electrode as a function of time and the polarizing potential in the case where a slow irreversible chemical reaction follows a reversible electron transfer reaction under the conditions of a somewhat idealized polarographic system.

Reversible electron transfer reaction of a freely diffusing species has been studied using the network approach. A network model for this process under cyclic voltammetric conditions has been proposed, and a numerical simulation has been made with the help of the electrical circuit simulation routine PSPICE. A great accuracy in simulated voltammograms has been reached with a personal computer at a moderate cost in computer time.

Three manganese biscorrole dyads were synthesized, physicochemically characterized and investigated as to their electrochemistry and spectroelectrochemistry in nonaqueous media. Each dyad contained the same two corroles linked in a face-to-face arrangement via one of the three different linking groups, 9,9-dimethylxanthene, anthracene or diphenylether, the exact nature of which determined the distance and possible interaction between the two metallomacrocycles. The initial compounds contained Mn ( III ) in their air stable form and were shown to exhibit two major redox processes, one being a Mn (III)/ Mn (IV) conversion and the other being either Mn ( III )/ Mn ( II ) or reduction at the conjugated macrocycle to give a Mn ( III ) corrole π-anion radical when the solvent was pyridine. The potentials and reversibility of each electron transfer reaction were shown to depend upon the solvent (pyridine, CH2Cl2 , or PhCN ), type of spacer separating the two macrocycles and/or the presence or absence of axial ligation. The site of each electron transfer was assigned on the basis of spectroscopic and electrochemical data and by comparison with reactions and properties of the monocorrole ( Mes2PhCor)Mn which was characterized in a previous publication and also examined in the current study under the same solution conditions as the newly investigated dyads. Some electrode reactions of the dyads were followed by coupled chemical reactions and these were also elucidated in the present study.
