Table 1. Time Constants for 1 Extracted by Global Lifetime Analysis of MA TA Spectra Pumped by 400 and 325 nm (Evolution-Associated Spectra Are Shown in Figure S5a,b)a.

  400 nm 325 nm
τ1 200 fs 170 fs
τ2 19.5 ps 4.7 ps
τ3 +∞ +∞
a

The long-lived component τ3 stems from the 5.7 ns fluorescence lifetime of 1, which is not resolved in the TA delay time window.
