Macrocyclic compounds play a major role in supramolecular chemistry because of their beautiful shape, nano-scale size and molecular recognition ability. Numerous supramolecular architectures have been constructed and studied as new components of materials as well as entities related to biological structural formation and functions using various macrocyclic hosts.

In 2008, we reported a new class of macrocyclic hosts named “pillar[n]arenes”.[1,2] Linear 1,2-dichloroethane and bulky chlorocyclohexane acted as template solvents for high-yield synthesis of pillar[5]- and pillar[6]arenes, respectively. They have unique symmetrical pillar structures due to their para-bridge linkage. We have synthesized various topological and functional molecules based on functionality of pillar[n]arenes, and constructed 2D sheets and 3D vesicles based on geometric assemblies of their pentagonal and hexagonal structures.[3]

Speaker information

Prof Tomoki Ogoshi, Kanazawa University, Japan. Tomoki Ogoshi received his B.S. (2000), M.S. (2002), and Ph.D. degrees (2005) from Kyoto University under the supervision of Prof. Yoshiki Chujo. He received JSPS research fellowships for young scientists (2002−2005). He was a JSPS postdoctoral research fellow (2005−2006) in the Graduate School of Science at Osaka University in the group of Prof. Akira Harada. In 2006, he moved to the Graduate School of Natural Science and Technology at Kanazawa University as an assistant professor (2006−2010). He was an associate professor (2010−2015) and was promoted to a professor at the same university at 2015. He works also as JST-PRESTO Researcher: PRESTO program “Hyper-nanospace design toward innovative functionality” since October of 2013 under the research supervisor of Prof. Kazuyuki Kuroda (Waseda University). His research interests include organic synthesis, and supramolecular and hybrid materials.
