N-(9-anthrylmethyl)-N’-(tropon-2-yl)diaza-18-crown-6 (4) gave a weak emission, showing that the excited anthracene chromophore was quenched by the diazacrown nitrogen atoms and tropone unit. Diazacrown (4) was found to display unique photophysical properties in the presence of metal salts. Diazacrown (4) exhibited Cu2+ selectivity and in the presence of this cation the host fluorescence intensity was increased by a factor of 7.8.
