A new quinoline-based chemosensor 1 has been designed and synthesised. Its metal ion-binding properties have been documented in organic and aqueous organic solvents. While chemosensor 1 recognises Hg2+ ions (K a=2.15x104M1) by exhibiting ratiometric change in emission in CHCl3/CH3OH (1:1, v/v), under similar condition both Zn2+ and Cd2+ ions are sensed by significant non-ratiometric increase in emission with measurable red shift. In DMSO/H2O (5:95, v/v), the sensor 1 exhibits a greater selectivity towards Hg2+ ions (K a=9.20x103M1) over the other metal ions examined.
