Finding suitable probes for the rapid and sensitive detection of highly toxic pollutants is an urgent challenge for our environment. In this paper, three Schiff base ligands (H2L1 = 2,6-diacetylpyridine bis(isonicotinoylhydrazone), H2L2 = 2,6-diacetylpyridine bis(nicotinoylhydrazone) and H2L3 = 2,6-diacetylpyridine bis(picolinoylhydrazone)) have been used as potential chemosensors for Cd2+ detection. The corresponding Cd(II) complexes were prepared and it was found that the chemosensors coordinate similarly to the Cd2+ ion, eventually exhibiting different photoluminescent responses. Coordination of H2L1 and H2L2 to the Cd(II) ion results in a “turn-off” photoluminescence, while coordination of H2L3 show an excellent example of a “turn-on” mode of photoluminescence. Moreover, all three studied ligands are appropriate candidates for a fast, simple and portable method of Cd(II) ion detection. |
