Excited state absorption spectra and intersystem crossing kinetics in diazanaphthalenes
Picosecond time-resolved, excited state absorption spectra in the visible following excitation at 355 nm are discussed for room temperature solutions of four diazanaphthalenes (DN)-quinoxaline (1,4-DN), quinazoline (1,3-DN), cinnoline (1,2-DN), and phthalazine (2,3-DN).Kinetics of singlet state decay are obtained by monitoring the decay of Sn <*> S1 bands.The intersystem crossing rate constant (kisc) is found to vary as kisc(1,4-DN)>kisc(1,3-DN)>kisc(1,2-DN).The kisc in phthalazine could not be determined from the weak, visible Sn<*>S1 absorption.Assuming rapid singlet vibrational relaxation and only minor effects due to energy gap variations, these experimental results agree with statistical limit predictions for the relative nonradiative rate.Calculations of the spin-orbit coupling matrix element betael =
