This paper studies the spectral-luminescent and lasing properties of several new 2-(4-pyridyl)-5-aryloxazoles with a varying substituent in the 5-phenyl radical, and their quarternary salts (II). The spectral-luminescent properties of the compounds synthesized were investigated by using a SF-4A spectrophotometer and a fluorescent apparatus based on a ZMR-3 monochromator with photoelectric recording. The absolute fluorescence quantum yields were determined by the equal absorption method. The absorption spectra of compounds I in 96% ethanol are not different in their character from an absorption spectrum of unsubstituted 2,5-diphenyloxazole (PPO). It is shown that the compounds studied are prospective for lasing emission in the 16,130-20,410 cm/sup -1/ region.
