Over the past century, adsorption has been investigated extensively in equilibrium systems, with a focus on van der Waals interactions associated physisorption and electronic case of chemisorption. In this study, we demonstrate mechanisorption, which results from nonequilibrium pumping to form mechanical bonds between adsorbent adsorbate. This active mode realized surfaces metal-organic frameworks grafted arrays molecular pumps. Adsorbates are transported one well-defined compartment, bulk, another interface, thereby creating large potential gradients chemical capacitors wherein energy is stored metastable states. Mechanisorption extends, fundamental manner, scope phenomena offers transformative approach control chemistry at interfaces.

Abstract Scientists have long been fascinated by the biomolecular machines in living systems that process energy and information to sustain life. The first synthetic molecular rotor capable of performing repeated 360° rotations due a combination photo‐ thermally activated processes was reported 1999. progress designing different intervening years has remarkable, with several outstanding examples appearing last few years. Despite accomplishments, there remains confusion regarding fundamental design principles which motions molecules can be controlled, significant intellectual tension between mechanical chemical ways thinking about describing machines. A thermodynamically consistent analysis kinetics rotors pumps shows while light driven operate power‐stroke mechanism, kinetic asymmetry—the relative heights barriers—is sole determinant directionality catalysis Power‐strokes—the depths wells—play no role whatsoever determining sign directionality. These results, elaborated using trajectory thermodynamics nonequilibrium pump equality, show asymmetry governs response many non‐equilibrium phenomena.
