Abstract :
This work presents the first observations of time-resolved photo-CIDNP in the dibenzyl-ketone-β-cyclodextrin (DBK–β-CD) inclusion complex. The photo-decay of the DBK–β-CD inclusion complex gives a benzyl radical that is held in the β-CD cavity for a time exceeding the time of its nuclear spin lattice relaxation. By estimating a change in the radical spin-lattice relaxation time in the complex, we determined that the rate constant of dissociation of β-CD complex with the radical is ⩽105 s−1.
