Pillar-Shaped Macrocyclic Compounds “Pillar[n]arenes”: from Simple Molecular Receptors to Bulk Supramolecular Assemblies
Description

Tomoki Ogoshi dec2017Macrocyclic 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]

There will be an opportunity to discuss the colloquium and other developments during an informal get-together with drinks directly afterwards on the third floor of the Huygens building between wings 1 and 2.

This lecture fits in the IMM Theme 2 Chemistry and Spectroscopy of Complex Molecular Systems colloquium series, in which researchers from IMM Theme 2 as well as high-profile researchers from outside Radboud University present work that is of interest to scientists across Theme 2. These lectures take place on the second Tuesday of every month and are open to everyone in who is interested.
