| Research Abstract |
In order to develop a technology which controls intense movement of molecular components by heat intentionally, a plan to create an asymmetrical rotaxanetype molecular brakes was planned. Syntheses of the components and immobilization onsupport were studied. First, an ideal intermediate stopper component having tripoly form was created and synthesized in large quantities. Next, seven kinds of axial molecules from which the length of a spacer portion differs were synthesized. Furthermore, a part of asymmetrical rotaxanes was synthesized, and an immobilization of rotaxane on a gold surface have been performed.
