Abstract: Using opto-acoustic spectroscopy, transient absorption spectroscopy and time-resolved fluorescence spectroscopy, it could be demonstrated that the rate constant for intersystem crossing of 3-(1-pyrenyl)-propylbromide is twice that of the model compound 1-methylpyrene. The effect of the intramolecular interaction between bromine and pyrene on the rate constant of intersystem crossing leads to a value that is still several orders of magnitude smaller than the rate constant for the intramolecular excimer formation of 1,3-di(2-pyrenyl)-propane or of intramolecular exciplex formation in 1-N,N-dimethylamino-3-(1-pyrenyl)-propane. This suggests that the contribution of the interaction between bromine and pyrene to the rate constant for intersystem crossing is considerably below the values expected for a process whose rate is limited by the rate of folding of the propyl chain.
