Aryloxazolyl-substituted rhodamine C derivatives

Aryloxazolyl-substituted rhodamine C derivatives were synthesized by condensation of 4-(5-aryloxazol-2-yl)phthalic anhydrides with m-diethylaminophenol, and their spectral-luminescence properties were investigated. The individual compounds and their mixtures with 4-aminonaphthalic acid phenylimide were used to obtain daytime fluorescent pigments and paints. Effective intermolecular transfer of the electronic excitation energy is observed in mix compositions, and its mechanism is discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1037–1041, August, 1982.
