Outline of Final Research Achievements

Molecular shuttles that operate using various stimuli, such as light etc, have attracted much attention because such switching systems might aid the development of molecular devices and molecular sensors of chemicals and so on. In this study, we accomplished a synthesis of five-state molecular switches (rotaxane and rotaxane system), which have multi components connected by mechanical bonds each other. The one component in the rotaxane reversibly underwent acid-base dependent switch from binding at original position to the other site of rotaxane.
