摘要：

New derivatives of 3-[2-(phenyl)benzoxazol-5-yl]alanine (Box-Ala) substituted at position 2' and 4' with OH, OMe, NMe2 groups were prepared. Fluorescence properties (spectra, quantum yields) of new compounds were determined and compared with parent molecules without amino acid moiety. It was established that fluorescence properties of known benzoxazoles and new ones are similar. In the case of 3-[2-(2'-hydroxyphenyl)benzoxazol-5-yl]alanine ((o-OH)Box-Ala), presence of many different tautomeric forms in the ground state were found depending on solvent used.
