Abstract:Laser flash photolysis studies (l = 355 nm) on the characterization and reactivity for the triplet excited state of 2-methoxythioxanthone, 2-benzyloxythioxanthone, and 2-(n-propoxy) thioxanthone revealed that the transients generated in their excitation, in acetonitrile, have absorption bands with maxima at 310 and 620 nm. These transients decayed by a mixed 1st and 2nd order kinetics, with a lifetime of 5.3 ms for 2-methoxythioxanthone and benzyloxythioxanthone and 3.9 ms for 2-(n-propoxy) thioxanthone.
