RIKEN Center for Emergent Matter Science Emergent Molecular Assembly Research Unit

Unit Leader: Hiroshi Sato (Ph.D.)

Research Summary

Hiroshi Sato(Ph.D.)

The aim of this unit is to unleash the potential of molecules by controlling their assembly and arrangement patterns, and to create novel functions that are impossible to achieve with single molecules. Our specific research themes are as follows.

  • (1)Creation of materials by precise arrangement of topological bonds: By periodically arranging topological bonds such as catenanes, we will realize new materials.
  • (2)Sequence control in supramolecular polymerization: In supramolecular polymerization, it is still challenging to control the monomer sequence, so we are trying to control the sequence in coordination polymers.
