Abstract

DESIGN AND SYNTHESIS OF NEW CHEMOSENSORS FOR METAL IONS HAS RECEIVED CONSIDERABLE ATTENTION BECAUSE THEY PLAY IMPORTANT ROLES IN LIVING SYSTEMS AND HAVE AN EXTREMELY TOXIC IMPACT ON THE ENVIRONMENT [1]. IN RECENT YEARS, MANY EFFORTS HAVE BEEN DEVOTED TO DESIGN OF VARIOUS CHEMOSENSORS SPECIFIC FOR NI2+ ION DETECTION [2]. THE MOST ATTRACTIVE APPROACH FOCUSES ON THE RESEARCH OF NOVEL COLORIMETRIC NI2+ ION SENSORS, WHICH ALLOW NAKED EYES DETECTION OF THE CHANGE OF COLOR WITHOUT RESORTING TO THE USE OF EXPENSIVE INSTRUMENTS [3].IN THE PRESENT WORK, WE HAVE EXPLORED A NEW DERIVATIVE OF AZO-AZOMETHINE WITH N2S2O2 DONORS SET OF ATOMS THAT DEMONSTRATING EXCELLENT SELECTIVITY TOWARDS NI2+ ION. THE AZO-AZOMETHINE LIGAND HAS BEEN SYNTHESIZED VIA CONDENSATION REACTION OF 1,2-BIS(2-AMINOPHENYLTHIO)ETHANE WITH 5-(4- CHLORO-PHENYL)-AZO-SALICYLALDEHYDE. THE NEW PREPARED SENSOR WAS WERE CHARACTERIZED BY IR, 1H NMR, MASS SPECTROMETRY AND ELEMENTAL ANALYSIS. THE PROPOSED SENSOR SHOWS A REASONABLE DISCRIMINATION ABILITY TOWARDS NI2+ ION IN COMPARISON TO SOME ALKALI, ALKALINE EARTH, TRANSITION AND HEAVY METAL IONS VIA DRAMATIC COLOR CHANGE FROM PALE YELLOW TO ORANGE WHICH CAN EASILY BE OBSERVED BY THE NAKED EYE. TO INVESTIGATE THE SELECTIVITY OF RECEPTOR, THE UV–VIS ABSORPTION SPECTRAL BEHAVIOR UPON THE ADDITION OF METAL ION WAS MONITORED (FIG.1).
