Dual fluorescence is described and characterized for several 9-substituted porphycenes. Using both spectroscopic and computational studies, the phenomenon is related to the differential stabilization of the two trans tautomers in the excited state. The electronic nature of the 9-substituents affects both the energy and the lifetime of the two tautomers as well as their interconversion. The results are consistent with a two-step model for excited-state tautomerization that involves the population of an upper excited state, tentatively assigned to a cis species, which in turn provides an efficient non-radiative pathway to the ground state.
