<p>features a rotaxane with a ring that can move across an "axle" between two ends or possible <a href="page.php?w=binding_site">binding site</a>s (<a href="page.php?w=hydroquinone">hydroquinone</a> units). This design realized the well-defined motion of a molecular unit across the length of the molecule for the first time. In 1994, an improved design allowed control over the motion of the ring by <a href="page.php?w=pH">pH</a> variation or <a href="page.php?w=electrochemistry">electrochemical</a> methods, making it the first example of an AMM.</p><p>
