本文用~ 1H NMR研究了中性2，6-二取代萘和对位二取代苯衍生物与环番的包结作用。这些配合物中主要的吸引性主客体相互作用是π-π堆积和边-面芳香相互作用。个别研究调查相对结合强度的函数（i）的电子性质的客人，（ii）的溶剂的性质，和（iii）的性质的cyclophane主机。在此基础上，合成了两个新的四氧杂[n.l.n]环芳，它们的芳醚键邻位带有8个甲氧基
This paper describes a comprehensive 1 H NMR analysis of the inclusion complexation of neutral 2,6-disubstituted naphtalene and para-disubstituted benzene derivatives by cyclophanes. The major attractive host-guest interactions in these complexes are π-π stacking and edge-to-face aromatic-aromatic interactions. Individual studies investigate relative binding strength as a function of (i) the electronic properties of the guests, (ii) the nature of the solvent, and (iii) the nature of the cyclophane hosts. For these investigations, two new tetraoxa [n.l.n] cyclophanes with eight methoxy groups ortho to the aryl ether linkages were synthesized
