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 <b>1</b> 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<sup>+</sup> ion-dipole interactions. In the presence of Cs<sup>+</sup>, chiral complexes of calixnaphtharenes <b>5</b> and <b>6</b> were observed in which the ...[more]
