摘要: 本文研究了15种新合成的单、双N取代二苯并18冠6的1H及13C NMR谱。结果表明,13C NMR谱的化学位移能显示分子的电荷分布,而1H NMR谱的偶合常数则部份地反映了大环的构象。氮原子的杂入大环结构和取代基的改变对聚醚环上的电荷分布影响的结果说明,这些改变可能会对冠醚的络合作用发生影响。

Abstract: In this work, the 1H and 13C NMR spectra of 11 kinds of firstly synthesized N-substituted benzo-15-azacrown-5 and 3 bis-a3acrown ethers in different concentractions were lecorded. Individual peaks were assigned. Some structural effects were also discussed.
