In the original Maxwell’s demon thought experiment, a potential gradient of particles between two neighbouring compartments is created without the apparent use of work. Now a functional example of this experiment where material is pumped over centimetres has been reported—o-fluoroazobenzene is transported unidirectionally under light stimulation between two arms of a U-tube across an aqueous layer containing coordination cages.
