Sažetak
The control of motion on the molecular scale is of fundamental importance for living organisms, but the construction of synthetic molecular machines able to operate autonomously and perform a specific task remains one of the most intriguing challenges in supramolecular chemistry and nanoscience. Here, we present a dissipative self-assembling pseudorotaxane system that utilizes light as external source of energy needed to perform directed molecular motion in a cyclic manner away from chemical equilibrium. Upon light irradiation, macrocycles are transported through the thread unidirectionally, making the system behave as a molecular pump. It operates by dissipating irradiation energy in an autonomous fashion and in accordance to both energy and information ratchet mechanisms. The described light-powered molecular pump can further be modified and expanded to a more complex architecture comprising a reservoir. In this way, in addition to pumping, the macrocycles can be trapped in the reservoir, in a higher energy state, once light of appropriate wavelength is shined on the system.
