摘要：

A novel simple C-3v-symmetric, completely water soluble quinoline based guanidinium Schiff s base system have been reported for the selective detection of Cd2+ in physiological environment through a turn-on fluorescence response. The cadmium complex is found to be highly selective toward iodide by turning off the fluorescence through the sequestration of Cd2+ from L-1-Cd by the precipitation of Cd2+. Detection limit for Cd2+ and iodide are found to be 51 ppb and 1 ppb, respectively. L-1 is reversible toward Cd2+ and iodide and can be recycled. The receptor was used for the detection of Cd2+ in complex natural samples (tap, lake and river water). (C) 2014 Elsevier B.V. All rights reserved.
