Abstrakt: Phthalonitirile-oxazol-5-ones (Pht-Ox), were synthesized with 4-(4-formylphenoxy) phthalonitrile and benzoylglycine derivatives. The original compounds prepared in the reaction pathway were characterized by the combination of FT-IR, 1  H and 13  C NMR, UV-vis and MS spectral data. achieved. To obtain the photophysical data of the synthesized Pht-Ox derivatives were used spectrophotometric and spectrofluorimetric methods. Evaluation of the absorption and emission properties of the structures was carried out in three different solvents. Maximum absorption and emission wavelengths (λ; nm), molar extinction coefficients (ε; cm - 1  M - 1 ) and Stoke's shifts (Δλ ST ; nm) of Pht-Ox derivatives were declared.
