Abstract
The chiral diaza-9-crown-3 derivative 1 is the first example of a fluorescent PET chemosensor designed specifically for detecting lithium ions (Li+). 1 shows ‘off–on’ switching of fluorescence when treated with various lithium salts in organic solvents such as CH3CN, with binding constant log β=5.4, at the same time as discriminating against a variety of group I and II metal ions. In water the emission is quenched by anions due to the heavy-atom effect.
