Fei Zeng, Lin-Li Tang, Man‐Hua Ding, Wubliker Dessie
Abstract
A novel stretched hexagon structure naphthalene diimides-extended-pillar[6]arene 1 with a giant cavity size of 18.769 Å in width and 17.109 Å in height is reported. 1 exhibits highly selective binding of pagoda[5]arene compared to pillar[5]arene and prism[5]arene. Size matching and charge transfer interactions play a key role in the formation of the ring-in-ring stable complex.
