    • Despite profound time-resolved data on the 7AI dimer, detailed ESDPT dynamics on other host/guest complexes have not yet been explored. In our experience, the lack of dynamical information might be in part due to the complication in preparing an optimum concentration of host/guest complexes to perform the ultrafast time-resolved measurements. Concentrated 7AI (and its corresponding analogues) results in an appreciable dimeric formation, which undergoes a competitive equilibrium with respect to the host/guest complex. One may consider adding excess acetic acid concentration to shift the equilibrium toward the complex formation. Unfortunately, the accumulation of a local polarity due to the aggregation of acetic acid leads to the excited-state protonation rather than double proton-transfer reaction.
