Two new selenium containing anthracene derivatives and two new sulfur containing anthracene derivatives were synthesized as fluorescent chemosensors; for Hg2+ and CU2+. Compound 1 displayed a highly selective chelation enhanced fluorescence quenching (CHEQ) effect only with Cu2+, on the other hand, compounds 3 and 4 displayed highly selective chelation enhanced fluorescence (CHEF) effects only with Hg2+ among the metal ions examined.
