Abstract
 A triple-probe channel type chemosensor based on an NO2S2-macrocycle functionalized with phenyltricyanovinyl group was synthesized and its sensing characteristics were examined. The pink-red solution of L changed selectively to pale yellow upon addition of Hg2+. The selective fluorometric response of L to all the tested metal ions was studied. The results showed that a large enhancement of the fluorescence of L was observed only in the case of Hg2+. In addition, L showed large anodic shift (~ 0.3 V) for the addition of excess Hg2+. Through above three observed results by the different techniques, we confirmed that the proposed chemosensor acts as the multiple-probe channel sensing material. The crystal structure of mercury(II) nitrate complexs of L which shows a 1-D polymer network with a formula [Hg2(L)2(NO3)2(μ-NO3)2]n was also reported.
