| 摘 要： | 采用分步法高产率地合成了系列新型对叔丁基杯6]双冠醚，并得到了除杯式与1，2，3－交替式构象之外的第3种稳定构象的杯6]衍生物：1，4－交替式杯6]-1,4-2,5-双冠醚。研究了它们对碱金属及脂肪胺离子的两相萃取性能，发现杯6]双冠醚具有与杯6]单冠醚不同的识别能力。

| Abstract: | By reacting calix-1,4-crowns with triethylene glycol ditosylates or 1,2-bis-tosyloxyethoxybenzene in NaH/DMF system, a series of new type of calixcrowns: p-tert-butylcaix-1,4-2,5-bis-crowns were synthesized in high yields of 70%, and it is found that this stepwise method is very effective for the syntheses of calix-bis-crowns. The conformations of the obtained calix-bis-crowns were discussed in detail and the third stable conformation of calixarene besides cone and 1,2,3-alternate conformation-1,4-alternate conformation was obtained. It was found that the identification properties of this calix-bis-crowns are utterly different from that of the analogous calixcrowns and compound 2b exhibits a high complexation selectivity towards n-PrNH + 3. |
