  摘要：

  中性主体瓜环[7]与一系列阳离子胆碱（R3NCH2CH2OR' +）及其膦鎓类似物（R3PCH2CH2OR' +）（R3 = Me3、Et3、Me2Bz，或R3N =奎宁环鎓，R' = H、COCH3、CO(CH2)2CH3、或PO3H）以及（±）-肉碱在水溶液中形成非常稳定的复合物。利用1H和31P核磁共振波谱学以及ESI质谱法研究了复合行为。客体分子的复合诱导化学位移变化清楚地表明了通过P(CH3)3+取代N(CH3)3+末端基团以及改变R的性质对客体相对于CB[7]腔体及其极性门户面羰基位置的影响。这一研究表明，无需利用芳香壁进行阳离子-π相互作用，即可实现水溶液中对胆碱的分子识别。
