Calix[2]naphth[2]arenes make up a new class of phenol-naphthalene hybrid macrocycles. X-ray studies show that calix[2]naphth[2]arene adopts a 1,2-alternate conformation. Alkali metal cations are complexed by the calixnaphtharenes in a 1,2-alternate conformation, by cation···π interactions with the naphthalene walls, and by RO···M ion-dipole interactions. In the presence of Cs, chiral complexes of calixnaphtharenes and were observed in which the cation is nested on one of the two faces of the macrocycle.
杯[2]萘[2]芳烃构成了一类新型的苯酚 - 萘杂化大环化合物。X射线研究表明，杯[2]萘[2]芳烃采取1,2 - 交替构象。碱金属阳离子通过阳离子···π相互作用与萘壁以及RO···M离子 - 偶极相互作用，以1,2 - 交替构象被杯萘芳烃络合。在铯存在的情况下，观察到杯萘芳烃的手性配合物，其中阳离子嵌套在大环两个面中的一个面上。
