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1HNMR、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.

关键词: 杯芳冠醚, 萃取, 硫, 硒

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 1HNMR, MS and elemental analysis. It was shown that the calix-heterocrowns exhibited a high selectivity for Ag+, Hg2+compared with Na+, K+, NH4+, Co2+and Ni2+.

Key words: Calixcrown, Extraction, Sulfur, Selenium
