| Research Abstract |
Molecular motors such as ATP synthetase are so-called "molecular motors" that utilize chemical bonding energy of ATP. The purpose of this project is to design and synthesize artificial supramolecular complexes, the structure of which are altered by enzymatic phosphorylation and dephosphorylation reactions. We have designed the rotaxane-like supramoleculer complexes that contain a macrocycle part (cyclodextrin (CyD)) and an axis part that is threaded through a CyD ring. In this work, we have succeed in the synthesis of the rotaxane molecule that contains an azobenzene unit as "Station " at the center of the axis and two Zn2+-cyclen complex units as "Station 2" at the edge of the axis.
