Shinkai et al. reported photoresponsive crown ethers (Figure 54) comprising two 15-crown-5 molecules linked by an azobenzene unit, which exhibited a butterfly-like motion. They found that the rate of the thermal isomerization was suppressed by added alkali metal cations and different alkali metal cations could be extracted efficiently by the different conformations of the molecules with high selectivity. These studies demonstrate that in principle ion extraction and ion transport through a liquid membrane can be controlled by light. Although this is not a mechanical molecular machine, it is considered as the prototype of early molecular machines and...
