Resolvation and fluorescence spectra of solutions of phthalimide derivatives in the binary solvent heptane-hexanol

Resolvation of 3-amino-N-methylphtalimide and 3-(dimethylamino)-N-metylphth alimide in the binary solvent heptane-hexyl alcohol was studied. The earlie r proposed spectrochemical method was used to obtain fluorescence spectra f or a series of solvate complexes of the aminophthalimides with hexanol mole cules, formed by primary elementary resolvation acts. The formation of the immediate environment of the phthalimide molecules was considered in terms of the structure of the latter. The regularities in the manifestation of th e reservation processes that occur under the combined effect of local (shor t-range) and bulk (polarization) intermolecular forces in the fluorescence properties of the ternary solutions studied was discussed.
