An exciting contemporary area of chemistry is making molecules with moving parts, with the<br />

goal that they can function as nanoscopic machines capable of performing physical tasks. To do<br />

so for any molecular machine more sophisticated than a simple switch requires the introduction<br />

of ratchet principles into synthetic molecular structures. We will <strong>di</strong>scuss some of the latest<br />

developments from our group in this area, inclu<strong>di</strong>ng the experimental realisation of both energy<br />

ratchets and information ratchets. [1]<br />
