Investigation of the fluorescence of H2-phthalocyanine

Electronic spectroscopy of phthalocyanine in a supersonic jet revisited

“…8 b Experiment in solution. 53 c DFTcalculation. 34 collimation by a skimmer and limited acceleration, argon is the favored carrier gas.…”

“…In solution the corresponding lifetime was measured to be about t E 6 ns. 53 While in general the lifetime is expected to be reduced in solution due to energy dissipation into the solvent, the solvent may modify the intersystem crossing rate of Pc in such a way that the excited state lifetime is found to be increased compared to the gas phase.…”
