Welcome to “Chemistry of Dynamic Molecules Laboratory” in Nagasaki University

In this article, the first, I introduce the roots and history of Chemistry of Dynamic Molecules Laboratory in Nagasaki University together with my previous works. Next, my recent three works, polyurethane elastomers crosslinked by polyrotaxanes, easily peelable pressure sensitive adhesives, and redox-active ionic liquids are described. Although it is not possible for you to visit my laboratory easily due to the serious situation of coronavirus infection, I hope you get a feel as if you were visiting my laboratory.
