ABSTRACT
Methylene blue shows an isotope dependent triplet lifetime that is 50% longer in D(2)O compared with H(2)O as a result of electronic-to-vibrational relaxation. The effect is enhanced when the dye is bound to curcubit[7]uril due to a combination of restricted mobility and a unfavorable vibrational coupling.
