Novel enantioselective fluorescent sensors for tartrate anion based on acridinezswsxa

This is the authors' abstract. We don't add key points for this paper.

Novel chiral fluorescence sensors L‐1 and D‐1 incorporating N‐Boc‐protected alanine and acridine moieties were synthesized. The recognition ability of the sensors was studied by fluorescence titration, 1H NMR spectroscopy and density functional theory (DFT) calculations. The sensors exhibited good enantioselective fluorescent sensing ability toward enantiomers of tartrate anion for the selected carboxylate anions and formed 1: 1 complexes by multiple hydrogen bonding interactions.
