摘要：
A sensitive fluorescent probe, 2,2'-bisbenzimidazole (L), for CN- has been developed. This structurally simple receptor displays great selectivity for the cyanide anion over other common inorganic anions in an aqueous environment. In addition, further study demonstrates the lower detection of the fluorescence response of the sensor to CN- is in 10(-9) mol/L range. Thus, the present probe should be applicable as a practical system for the monitoring of cyanide concentrations in aqueous samples. (C) 2013 Tai-Bao Wei.
