中文摘要：

合成了上缘含双吲哚基团的杯[4]芳烃衍生物5,17-双吲哚甲基-25,27-二丙氧基-26,28-二羟基杯[4]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Hg^2＋具有良好的选择性,向主体2的溶液中加入Hg^2＋离子,其吸收光谱在500nm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＋.

英文摘要：

A calix[4]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.
