【摘要】 从简单无机硫、硒化合物直接合成冠醚环上含硫、硒杂原子的杯［４］单硫杂冠－５ 及杯［４］单硒杂冠－５； 化合物的结构经１Ｈ ＮＭＲ、ＭＳ及元素分析确证． 并研究了它们对Ｎａ＋ ， Ｋ＋ ， ＮＨ４＋ ，Ｃｏ２＋ ， Ｎｉ２＋ ， Ａｇ＋ 及Ｈｇ２＋ 的两相萃取性能， 发现其对Ａｇ＋ 、Ｈｇ２＋ 有较好的识别能力更多还原

【Abstract】 The synthesis of calix[4]monothiocrown 5 and calix[4]monoselenocrown 5 with sulfur and selenium incorporating into poly(oxyethylene) chains was described. Their structures were confirmed by 1H NMR, MS and elemental analysis. It was shown that the calixheterocrowns exhibited a high selectivity for Ag +, Hg 2+ compared with Na +, K +, NH 4 +, Co 2+ and Ni 2+ .更多还原
