英文摘要 | A new calix[4]arene-based fluorescent chemosensor bearing- four dansyl amides on the upper rim (1) was conveniently synthesized. which showed hi-h sensitivity and selectivity toward hg(2+) over a wide range of metal ions in 50% aqueous acetonitrile. the complexation of hg(2+) ion induced a strong fluorescence quenching of 1 due to a well-defined electron transfer process from the dansyl group(s) to the metal center. compared with compounds 2 and 3. tetradansyl amide substituted calix[4]arene 1 showed a preorganized and coordinated complexing site for metal ions. moreover, the detection limit for hg(2+) was found to be 3.41 x 10(-6) mol center dot l(-1), which might make 1 a potentially practical hg(2+)-selective fluorescent sensor in aqueous system. |
