Abstract :
We present the first study of double proton-transfer reactions of a guest, 7-hydroxyquinoline (7HQ), with water at both gates of cyclodextrins. The photoinduced double proton-transfer dynamics in the caging capsule (caged dynamics) is markedly slower than that in pure water (free dynamics). The deprotonation rate of caged 7HQ is found to be 14 times faster than that of caged 2-naphthol.
