Summary of lifetimes generated from the global fittings using the Glotaran software.41 Errors are half the FWHM of the instrument response function (TEAS) (see ESI Table 5) or standard errors obtained from the Glotaran fits (TVAS).
| Lifetime | TEAS | TVAS | ||
|---|---|---|---|---|
| Thiomaleimide 1 | Bis-thiomaleimide 4a | Thiomaleimide 1 | Bis-thiomaleimide 4a | |
| τ 1 S2 (π1π*) → S1 (n1π*) | 2.9 ± 0.1 ps | 2.7 ± 0.1 ps | 2.7 ± 0.1 ps | 2.9 ± 0.2 ps |
| τ 2 S1 (n1π*) → T | 20.5 ± 0.1 ps | 23.0 ± 0.1 ps | 18.9 ± 0.5 ps | 23.7 ± 0.9 ps |
| τ 3 T → T* | ≫2.5 nsa | >2.5 nsb | >2.5 nsc | 2.4 ± 0.1 ns |
a
The lifetime extracted from the global fit is 80 ns; however, this is significantly greater than the experimental time window of 2.5 ns and thus cannot be quoted with confidence.
b
The lifetime extracted from the global fit is 4 ns; this is just outside the experimental time window of 2.5 ns and hence cannot be reported with confidence.
c
The lifetime extracted from the global fit is 5 ns; this is just outside the experimental time window of 2.5 ns and hence cannot be reported with confidence.
