Table 2. Lifetimes (in picoseconds) for the ICT and TICT States of L1 in Different Solvents.
solvent | ICT | TICT |
---|---|---|
MeCN | 1550 | 100 |
MeOH | 450 | 50a |
DMSO | 1400 | 175 |
formamide | 110 | |
dioxane | 1100 | |
benzene | 790 | |
toluene | 650 | |
THF | 2400 | |
CHCl3 | 2800 | |
PMMA | 3500 |
The TICT lifetime in MeOH is below the instrument response function of the SPC setup.
