Triplet-triplet absorption spectra for these carbonyl compounds in [bmim.PF6] are similar to those observed in organic solvents. The triplet lifetime for thioxanthone in desogygenated samples is very long (71 μs), whereas in oxygen-saturated solution is 500 ns, which indicates the low oxygen solubility in this solvent. For benzil, lifetimes of 10 μs in [bmim.PF6] and 3.8 μs in acetonitrile were obtained. The decay for triplet thioxanthone and benzil follows a clear first order kinetics in [bmim.PF6], from which one can conclude that triplet-triplet annihilation is not an important decay process in this solvent.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-11-21T12:45:42Z No. of bitstreams: 1 40.pdf: 323132 bytes, checksum: 9e4f85e56e5cb8343fbe7bce04ebc4c3 (MD5)Made available in DSpace on 2011-11-21T12:45:42Z (GMT).
