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