X-ray diffraction analysis and luminescence spectral study of crystal solvates of N-(N'-tosylanthranoyl)anthranilic acid with acetic acid and dimethylformamide

摘要

Two crystal modifications of N-(N'-tosylanthranoyl)anthranilic acid were studied by X-ray diffraction analysis and luminescence spectroscopy. One crystal modification is a crystal solvate with acetic acid and is characterized by green fluorescence. Another modification is a crystal solvate with DMF and exhibits blue fluorescence. The modifications differ in the melting point.
