Pillar[5]- and pillar[6]arene-based supramolecular assemblies built by using their cavity-size-dependent host-guest interactions

Pillar[ n ]arenes, which we first synthesized and named in 2008, are new pillar-shaped macrocyclic hosts.

Summary:Pillar[ n ]arenes, which we first synthesized and named in 2008, are new pillar-shaped macrocyclic hosts. Pillar[ n ]arene homologues with n = 5-10 have already been synthesized, but the cyclic pentamers, i.e. , pillar[5]arenes, and cyclic hexamers, i.e. , pillar[6]arenes, have been most widely used because these can be obtained in good yields. To date, nearly all pillar[ n ]arene-based supramolecular assemblies have been constructed using pillar[5]- and pillar[6]arene scaffolds. In this feature article , we describe supramolecular assemblies built using host-guest interactions depending on the cavity sizes of pillar[5]- and pillar[6]arenes. We first discuss the effects of the type of substituents on the rims of pillar[5]- and pillar[6]arenes on their solubilities, functionalities and host-guest properties. We then discuss supramolecular assemblies based on their host-guest properties and pillar-shaped architectures. We discuss various pillar[5]- and pillar[6]arene-based supramolecular assemblies built using their host-guest interactions.
Bibliography:Tada-Aki Yamagishi received his MS degree (1985) in industrial chemistry from Kanazawa University and PhD degree (1989) in polymer chemistry from Kyoto University. He was an assistant professor (1988-1997) at the Faculty of Engineering, Kanazawa University, and a postdoctoral fellow at Nice-Sophia-Antipolis University in France (1992-1993), an associate professor (1997-2009) and was promoted to a professor at the Graduate School of Natural Science and Technology, Kanazawa University. He received The Japan Thermosetting Plastics Industry Association Award in 2008. His current interests include synthesis and physical chemistry for highly-functional and performance polymers, designed supramolecular chemistry and hybrid materials.
