The adsorption of molecules onto a surface from solution generally proceeds spontaneously by means of an equilibrium process. Now, it has been shown that macrocycles can be pumped onto a MOF substrate through the formation of mechanical bonds in a ratcheting mechanism that results in an out-of-equilibrium state.
