Quantum switching of π-electron rotations in a nonplanar chiral molecule by using linearly polarized UV laser pulses.

摘要: Nonplanar chiral aromatic molecules are candidates for use as building blocks of multidimensional switching devices because the π electrons can generate ring currents with a variety directions. We employed (P)- 2,2'-biphenol four patterns π-electron rotations along two phenol rings possible and theoretically determine how quantum be realized. found that each rotational pattern driven by coherent excitation electronic states under conditions: one is symmetry other their relative phase. On basis results dynamics simulations, we propose control method sequential among performed using ultrashort overlapped pump dump pulses properly selected phases photon polarization The serve theoretical design confined ultrafast nonplanar further current-induced magnetic fluxes more sophisticated systems.
