• The electronic interaction of both ground-state and excited-state <I>m</I>-aminoacetophenone (MAAP) with several aliphatic alcohols in nonpolar viscous solvent was investigated by steady-state and nanosecond fluorescence spectroscopies. Concentration dependence of several alcohols in liquid paraffin-hexane (LPH) mixed solvent upon fluorescence and absorption spectra suggests a complex formation of MAAP with aliphatic alcohols in the ground state. In the typical LPH solution of MAAP containing high concentration of alcohol, the complex fluorescence exhibits two-component decay and a longer wavelength fluorescence than the complex fluorescence exhibits a rise and decay. The results demonstrate that the complex in the excited state further associates with alcohol to make an exciplex including an alcohol molecule.
