COMPLEXING PROPERTIES OF 4-AMINONAPHTHALIMIDE CONTAINING AZADITHIA-15-CROWN-5 ETHER MOIETY WITH METAL CATIONS

Design and study of optical sensors for detecting cations are rapidly developing areas of supramolecular chemistry. In this paper we investigated the optical effects which 4-aminonaphthalimide containing azadithia-15-crown-5 ether moiety shows when complexing with metal cations in aqueous medium. A significant fluorescence enhancement is observed when the ligand coordinates with Hg2+ ion. This optical effect is a result of inhibition of photoinduced electron transfer process. Sensor has a good selectivity towards mercuric ions and it’s detection limit is small enough, so it is suitable for practical use.
