Abstract

Modifications occurring in the fluorescence and excitation spectra of 3-monoethylamino-N-methylphthalimide (3 MANP) dissolved in nonpolar solvents (-hexane and methylcyclohexane) as a function of added n-butanol and n-propanol between -90 and 90°C were measured. The modifications were due to the presence of two types of centres resulting from the interaction of the solvent molecules with the nonpolar solvent on the one hand, and with the polar solvent on the other. The mixed complex character of the fluorescence band was not affected by the concentration of the solution in the range 10-7−5 x 10-4 mol/l. An attempt was made to establish a relationship between the emission due to the centres resulting from the interaction with the alcohol molecules and the association degree of the respective molecules.
