Abstract Anthracene- d - and l -phenylalanine compounds ( 1 , ) were obtained in high yields by the condensation reactions of 9-anthraldehyde with reduction sodium borohydride. Both show luminescence solution solid states, exhibiting dual-state emission property. Solid samples exhibit mechanochromic enhancement grinding. In respect chiroptical property, display mirror-image circular dichroism spectra solution, KBr pellets circularly polarized a dissymmetry factor −1.4 × 10 −4 /6.0 respectively. The two can differentiate enantiomers free amino acids such as phenylalanine, lysine, glutamic acid folic acid, aqueous phase.
