Abstract
A number of aryloxazol-5-ones were synthesized by condensation of aromatic aldehydes with hippuric acid and substituted hippuric acids. Most of the products have intense luminescence in the solid state; all of them have luminescence in toluene at 77°K. Lengthening of the conjugation chain in the oxazolone molecules leads to a shift in their luminescence to the long-wave region. The compound that contains a conjugated system including two oxazolone rings also luminesces intensely in toluene at room temperature.
