Exciplex formation in 2-propanol solutions of imidazo[4,5-f]quinolines
The association of the excited state derived from four imidazo[4,5-f]-quinolines with 2-propanol in cyclohexane has been studied. The unusual bathochromic shift and bandwidth of the fluorescence spectra of these heterocyclic compounds in 2-propanol—cyclohexane solutions compared with those obtained in cyclohexane solutions have been attributed to the association of the excited state imidazoquinolines with the 2-propanol molecules. Hydrogen bonding between the imidazole NH moiety of the excited state imidazoquinolines and the 2-propanol is shown to be responsible for the association.
