Graphical representation of a rotaxane. Noun [edit] rotaxane (plural rotaxanes) A complex of two molecules, one ring-shaped and the other dumbbell-shaped, with the dumbbell threaded through the ring and having end groups too large to pass through the ring. Derived terms [edit] oligorotaxane; polyrotaxane; pseudorotaxane; Translations [edit]
Mar 15, 2023 · Through molecular mechanics using the force field along with the quantum dynamical aspect of mechanically interlocked compounds, rotaxanes (defined as macromolecular rings that are threaded on a dumbbell-shaped axle molecule) are investigated with advanced quantum mechanical methods, including the atom-centered density matrix propagation simulation technique, at different temperatures like 300 ...
