A series of chiral ferrocene-containing thioureaderivatives have been synthesized, and their enantioselective recognition properties were investigated by UV/Vis titration. Receptors 5a and 6a exhibit excellent chiral recognition abilities towards N-acetylaspartate. The differences in solution colour can be observed directly by the naked eye. The minimum energy structures of 5a and 6a were also obtained
