Applications of Pillar[n]arene-Based Supramolecular Assemblies

Abstract

Macrocycles are an important player in supramolecular chemistry. In 2008, a new class of macrocycles, "pillar[n]arenes", were first discovered. Research efforts in the area of pillar[n]arenes have elucidated key properties, such as their shape, reaction mechanism, host-guest properties, and their versatile functionality, which has contributed to the development of pillar[n]arene chemistry and their applications to various fields. This Minireview describes how pillar[n]arene-based supramolecular assemblies can be applied to supramolecular gel formation, reactions, light-harvesting systems, drug-delivery systems, biochemical applications, separation and storage materials, and surface chemistry.

Keywords: drug delivery systems; host-guest chemistry; macrocyclic compounds; pillar[n]arenes; supramolecular chemistry.
