• Anthracene-labeled symmetric chiral sensor
• Enantioselective recognition
• Sensing of L-tartrate
• Fluorometric discrimination
• Pyridinium amide
• L-Valine as chiral source

A new anthracene-based chiral chemosensor 1 has been designed and synthesized. L-Valine has been used as the chiral source in the design. The chemosensor 1 has been established as an efficient enantioselective sensor for L-tartrate. While in the presence of L-tartrate the fluorescent sensor 1 in DMSO exhibits considerable increase in emission, the isomeric tartrate brings relatively small change. The enantiomeric fluorescence difference ratio (ef) has been determined to be 29.38.
