Conversion from Pillar[5]arene to Pillar[6?15]arenes by Ring Expansion and Encapsulation of C_(60) by Pillar[n]arenes with Nanosize Cavities

摘要

Conversion of ring size from pillar[5]arene to pillar[6?15]arenes and isolation of pillar[n]arene homologues (n = 11?13) with known pillar[n]arene homologues (n = 6? 10) are demonstrated. Pillar[10]arene formed the most stable host?guest complex with C_(60) among the pillar[5?14]arenes.
