Supramolecular Network Structures Based on Pillar[n]arenes

Abstract

In 2008, the authors have reported “Pillar[n]arenes,” which were cyclic phenolic compounds. They are soluble in common organic solvents, thus can be functionalized by various organic protocols. Based on the functionality, they were used not only for host-guest chemistry, but also for engineering. In particular, because pillar[n]arenes are polygonal shapes such as regular pentagon and regular hexagon, it is easy to prepare assemblies with uniformed structures. In this review, first, the authors discuss synthesis and functionalization of pillar[n]arenes. Then, the supramolecular networks constructed by pillar[n]arenes are discussed.
