Resolvation and Fluorescence Spectra of Solutions of Phtahlimide Derivatives in the Binary Solvent Heptane-Hexanol

摘要

Resolvation of 3-amino-N-methylphtalimide and 3-(dimethylamino)-N-methylphthalimide in the binary solvent heptane-hexyl alcohol was studied. The earlier proposed spectrochemical method was used to obtain fluorescence spectra for a series of solvate complexes of the aminophthalimides with hexanol molcules, 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 the resolvation processes that occur under the combined effect of local (short-range) and bulk (polarization) intermolecular forces in the fluorescence properties of the ternary solutions studied was discussed.
