| 摘 要： | 合成了上缘含双吲哚基团的杯芳烃衍生物5,17-双吲哚甲基-25,27-二丙氧基-26,28-二羟基杯芳烃(2), 通过UV-Vis光谱研究了它对各种金属离子的化学传感行为. 结果表明, 主体2对Hg2+具有良好的选择性, 向主体2的溶液中加入Hg2+离子, 其吸收光谱在500 nm左右出现了一个新的吸收峰, 同时溶液颜色也由无色变为橙色. 因此, 化合物2有望作为一种新型的化学传感器用于检测Hg2+.

| Abstract: | A calix4]arene derivative(2)possessing bis(indolyl)groups was synthesized in satisfied yield,and further its response to metal ions was investigated by the means of UV-Vis spectrometry.The results obtained show that host 2 displays a high sensitivity to Hg2 .The addition of Hg2 made the absorption spectrum of host 2 appear a new band around ca.500 nm,and caused obvious color change of solution from colorless to orange-yellow.Hence,the detection of Hg2 can be easily found by naked eyes.Calixarene 2 may be used for the application as Hg2 -selective chemosensor,even in aqueous solution. |
