Transient Absorption Lifetimes at the Indicated Wavelengths Using λex=355 or 532 nm
| Cmpd | τTA, ns [λ, nm]; λex=355 nm | τTA, ns [λ, nm]; λex =532 nm |
|---|---|---|
| 1 | 6 [420], 20 [360, 420, 540] | 20 [357, 547, 670] |
| 2 | 5–8 [430, 540], 21 [540] | 20 [367, 537, 700] |
| 3 | 6 [640], 23 [530, 640] | 21 [357, 480, 640] |
| 4 | 10 [660]a, 110–120 [440, 660], 4000–5000 [440, 660] | 10 [357, 437, 657]a, 110–130 [357, 437, 657], 4500–6300 [437, 657] |
These lifetimes were associated with signal growth rather than decay.
