Abstract

Hydrogen-bonded complexes of 2-naphthol-triethylamine have been studied in polar solvents. The ground-state equilibrium constants and excited-state Stern-Volmer quenching rates have been calculated. Time-resolved emission spectra and the decay-associated spectra have shown that in the excited state, the usual proton-transfer reaction takes place in which a rise time in the kinetic curves of the fluorescence of the exciplex and a large red shift in the spectrum are observed.
