Exclusions of aromatic radical cations from cyclodextrin nanocavity studied by pulse radiolysis

Article Abstract:

The influence of hydroxypropyl-beta-cyclodextrin (HP-Beta-CD) on the one-electron oxidation reaction of aromatic sulfides (S) with Br2(sub .-) and the decay process of the S radical cation [S(super .+)] was investigated by pulse radiolysis. The dissociation kinetics of [S(super .+)] from the CD cavity was examined in terms of the apparent equilibrium constants for the formation and decay processes of [S(super .+)].

Inhibition of the formation and decay of stilbene core radical cations by the dendron during the photo induced electron transfer

Article Abstract:

The formation and decay processes of stilbene core radical cation (ST.(super +)) during the photo induced electron transfer are studied for a series of stilbeen bearing benzyl ether-type dendrons (D). ST.(super +) and the radical cation of peripheral dendron (D.(super +)) were generated by intermolecular hole transfer from biphenyl radical cation.
