摘要: The excited-state dynamics of Ru(II) (TPP) (CO) (acetone) (TPP = tetraphenylporphyrin) was investigated by using a sub-5-fs pulse, In previous studies, the fluorescence lifetime of Ru(II)-(TPP)(CO) could not be resolved and was reported to be <1 ps. Analysis of the six-coordinate complexes of Ru(II)(TPP)(CO)(acetone) showed that (1)Q(x)(pi,pi*) had a lifetime of 140 +/- 20 fs and the lifetime of (3)(d,pi*) was 560 +/- 150 fs. Stimulated emission due to a spin-forbidden transition from (3)(pi,pi*) to the ground state was observed for the first time. (C) Wiley-VCH Verlag GmbH & Co. KGdA, 69451 Weinheim, Germany, 2008)
