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-PrNH3+.

Key words: Calix-bis-crown, Syntheses, Conformation, Identification properties
