Abstract:
Molecular motors with particular structures can transfer certain input energy into orderly intramolecular motion under artificial controls and thus have potential applications in many fields, such as sustainable energy development and medical care devices. To facilitate appropriate molecular motor designs, we present a straightforward method that is based on atomistic quantum mechanics calculations, namely through vector summation of the torque acting on each atom and projected onto the rotational axis, so as to optionally inspect the impact of a certain part within a motor on the unidirectional rotation with explicit rotation direction and magnitude. A few examples will be given as demonstrations of the effectiveness of the approach. Our computational approach can in general provide insights into the unidirectional rotation ability of many molecules and help to theoretically screen or modify them in advance of experiments.
