摘要：

The initially formed viologen radical cation (V-.+) is further reduced to yield neutral viologen (V-o) by Ru(bpy)(3)(2+) sensitized photochemical reduction. By the reactions with water, 75-80% of V-o is reoxidized to V-.+ and the remainder is destroyed. The decreasing order of the reactivity is V-o in the absence of beta-cyclodextrin (beta-CD) > V-o in the presence of beta-CD > V-o covalently bound to beta(-)CD.
