A new acridine derivative was synthesized as a fluorescent chemosensor for Zn2+ in an 100% aqueous solution. Compound 1 displayed a selective CHEF (chelation enhanced fluorescence) effect with Zn2+, on the other hand, a similar anthracene derivative 2 did not display any significant change with the metal ions examined.
