RESUMO
[structure: see text] Optically active artificial host molecules 2-5 based on a phenolphthalein skeleton have been prepared for visual enantiomeric recognition of alanine derivatives 8 and 9. The receptor 3 discriminates (R)-8 and (R)-9 from (S)-8 and (S)-9, respectively, to develop a purple color.
