Upon a closer look at data shown in Figure , one can notice that, while the observed changes' trends follow the expectations, their quantitative evolution with increasing field strength diverges from the linear behavior predicted on the grounds of the dipole model. First of all, after initial destabilization under the weak electric field, the S form energy ceases to increase for field intensities greater than 0.005 a.u. Secondly, while for weaker fields the energy maximum along the switch rotation path does not undergo noticeable changes, at | ⃗ E| of about 0.004 a.u. lowering of the barrier starts to be observed. These findings indicate that, at intensity of about 0.004-0.005 a.u., the electric field becomes strong enough to make the higher-order electric effects (such as molecular polarizability) dominate over the linear (dipole) effect in the investigated PFCN system. Nevertheless, the resulting combination of effects leads to promotion of the desired electric-field induced chirality inversion. Finally, it should also be underlined that the investigated electric-field intensity range falls well within technical capabilities of dedicated equipment used, e.g., in electro-catalytic studies. In terms of the required voltage, the 0.008 a.u. electric field intensity corresponds to roughly 4 V/nm. Hence, switching a single layer of motors resembling the PFCN properties could be technically rendered possible already with a scanning tunneling microscope (STM) setup.
