摘要：

Chemical sensors based on optical signal detection are of increasing importance. Optical sensors of bulk optodes have the advantage of being robust and showing a highly reversible response explainable by means of the chemical equilibria involved. Therefore, a great number of new ion-selective bulk optodes have reported within a few years. Several sensors for detecting toxicologically revalant ions,such as Pb2+,Ag+,Hg2+ and UO22+ have been developed recently and exhibit the low detection limit required. Although a number of ionophores have been used in optodes and ISEs,the sensors described so far are inadequate for monitoring Ag+ in water, especially in drinking water because of their limited selectivity and/or insufficient sensitivity. More recently Pretsch et al designed and synthesized an improved optical sensor, methylene bis(2-thiobenzothiazole),which was Ag+-selective. Here we report synthesis of another ionophore,1,2-bis(2-thiobenzothiazole) ethane, and its IR, ESI-MS, 1HNMR and UV-Vis.
