  杯[6]芳烃基单分子笼状化合物的客体包合特性。由于它们具有高的Cs +和Ag +选择性以及非常慢的金属交换速率

  摘要：

  1,3,5-三-O-烷基烷基杯[6]芳烃与1,3,5-三（溴甲基）苯的反应生成了封端的杯[6]芳烃（2个在上边缘带有叔丁基的芳烃）3个不含叔丁基的化合物），出乎意料的高收率（80 – 91％）。通过MM3计算，X射线分析和1 H NMR光谱对2和3进行的联合研究表明，这些杯[6]芳烃具有独特的结构，该结构由三个均三聚的均三甲苯基连接的苯基单元和三个直立的苯甲醚交替排列组成单位。特别地，化合物2具有封闭的离子载体腔：上半球被三个封闭苯甲醚单元和下半球的叔丁基被1，3，5-三甲苯基帽和三个苯甲醚甲氧基封闭。的1 H NMR谱在宽的温度范围（30〜130℃），几乎没有变化，这表明结构极其刚性化。溶剂萃取和光谱学研究均证实，该空腔在碱金属阳离子中显示出对Cs +的高选择性，与Ag +的高亲和力以及与RNH 3 +的中等亲和力。非常令人惊讶的是，2-苦味酸铯与铯的缔合-解离过程是如此缓慢，以致于传统

  Synthesis and NMR Spectroscopic Studies of Bridged and Capped Calix[6]arenes: High-Yield Syntheses of Unimolecular Caged Compounds from Calix[6]arene

  摘要：

  Calix[6]arenes were bridged with a xylenyl unit or capped with a mesitylenyl unit, and their conformational properties were examined by spectroscopic methods. As previously reported by Gutsche et al., the calix[6]arene bridged on 1,4-phenyl units could enjoy slow ring inversion. The calix[6]arene bridged on 1,a-phenyl units also showed the ring inversion behavior, whereas in the calix[6]arene bridged on 1,3-phenyl units, ring inversion was virtually suppressed because of destabilization of the transition state. The capping of 1,3,5-tri-O-alkylated calix[6]arenes with 1,3,5-tris(bromomethyl)benzene gave the products in high yields (80-91%). This advantage was accounted for by the C-3 symmetrical complementarity of these two reactants. In these capped products, ring inversion was inhibited under the present measurement conditions, and the presence of a unimolecularly closed inner cavity was suggested on the basis of H-1 NMR spectroscopy and MM3 calculations.
