Nature embeds some of its molecular machinery, including ion pumps, within lipid bilayer membranes. This has inspired chemists to attempt develop synthetic analogues exploit membrane confinement and transmembrane potential gradients, much like their biological cousins. In this perspective, we outline the various strategies by which machines─molecular systems in a nanomechanical motion is exploited for function─have been designed be incorporated membranes utilized mediate transport. We survey machines spanning both switches motors, those that act as mobile carriers or are anchored membrane, mechanically interlocked molecules, examples activated response external stimuli.

Pumping ions against a concentration gradient through protein-based transporters is cornerstone of numerous biological processes. Mimicking this function by using artificial receptors remains daunting challenge, mainly because the difficulties in balancing between requirement for high binding affinities and precise on-demand ion capture release properties. We report trimeric hydrazone photoswitch-based receptor that converts light energy into work actively transporting chloride anion dichloromethane liquid membrane, functioning as molecular pump. The system manifests ease synthesis, bistability, excellent photoswitching properties, superb ON-OFF properties (difference up to six orders magnitude).
