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 calixarene 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.

Key words: Calixarene, Hg2+, Chemosensing, Bis(indolyl)
