Fig. 1: Working cycle and potential energy surfaces of a classical 4-stroke LDRM.
From: Impact of solvation on the photoisomerisation dynamics of a photon-only rotary molecular motor
a The main structures in the mechanism of the motor detected experimentally in ref. 3. b Profiles of the S1 (the red curve) and S0 (the blue curve) potential energy surfaces along the rotation path. The main structures are shown by the red and blue dots, accompanied by 3D geometries (without hydrogens) and conformational labels. The hourglass symbols show the positions of conical intersections (CI). The curved greyscale arrows show the sequence of geometric transformations. The straight upward magenta arrows show the photoexcitation events. The 3D structures shown in the figure were plotted using the data from ref. 27.
