Synthesis and Spectroscopic Properties of Oxazol-5-one- Substituted Phthalonitrile: A Novel Precursor for the Synthesis of Phthalocyanines

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 (& lambda;; nm), molar extinction coefficients (& epsilon;; cm(- 1) M- 1 ) and Stoke's shifts (& UDelta;& lambda;(ST); nm) of Pht-Ox derivatives were declared.
