Laser flash photolysis of trans-n-styrylquinoxaline - Chul Shim, S.; Sup Kim, M.; Taek Lee, K. (Elsevier)
Nanosecond laser flash photolysis of two n-styrylquinoxalines (n = 2, 6; 2-StQx and 6-StQx) produced strong transient absorption bands of the lowest transoid triplet state in the visible region at room temperature. The transient of 6-StQx shows first-order decay with a lifetime of 110-135 ns, whereas that of 2-StQx shows biexponential decay with lifetimes of 90 ns and 1.3 μs. The lowest triplet state of n-StQx lies between 42.0 and 47.0 kcal mol^-.
