Abstract

A reduced form of a synthetic hydrogen-assembled molecular shuttle for nano-technological applications has been investigated by molecular dynamics simulations and density functional theory calculations. It is composed by a benzylic amide macrocycle mechanically locked onto a thread in acetonitrile solution. Classical sampling indicates, in agreement with experimental findings, that in equilibrium condition at 298 K the macrocycle and the naphthalimide radical anion moiety within the thread strongly interact forming four strong OCN–H–OCNR hydrogen bonds. Simulations also revealed that the geometry of the supramolecular assembly reversibly oscillates between unfolded and folded conformations, with the latter characterized by an electrostatic hook involving the succinamide end group and the macrocycle itself. Finally, the simulated UV-Vis absorption spectra for free and complexed reduced naphthalimide quantitatively confirm that the transient spectroscopic change experimentally used as a probe for monitoring the translational motion of the macrocycle, from succinamide to naphthalimide stations, accompanying the selective electrochemical reduction.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
