摘要

The ligand 2,in which three fluorogenic 6-Methoxy-1-methylquinolinium fragments are apended to a mesityl platform,in MeCN forms 1:1 adducts with halides and other inorganic anions.~1H NMR studies and moecular modelling indicate that 2 provides a cavity for anion inclusion and establishes electrostatic interactons with the guest.Anion incluson indues quenching of the fluorogenic fragments with an efficiency decreasing along the series Br~-I~->NCS~-Cl~->NO_3~->HSO_4~-.The fluorimetric resonse of 2 to anions is orders of magnitude more sensitie than that of just 6-Methoxy-1-methylquinolinium,ligand 1.
