Based on these results we propose a mechanism for the reaction of BzV2+, BzV+ and BzV.
As shown in figure the second reduction peak is sharp due to extensive deposition of BzV and this neutral deposit is oxidized back to large anodic peak which is well removed to its cathodic partner.
It means that the reaction of BzV+ and /or BzV with bCD is reversible.
For second redox process it may be concluded that bCD does not bind with BzV.
