Given the ultimate goal of using molecular motors for practical applications, it is of interest to consider performance metrics to be optimized when designing them. One obvious metric is the rotation speed. There have been considerable efforts to make faster alkene motors, as reviewed from both experimental and theoretical perspectives . These have focused on accelerating THI, which is the rate-determining step of the rotational cycle, without sacrificing unidirectionality. The THI rate constant can be measured experimentally by monitoring the relaxation of the absorption spectrum after pulse excitation . It can also be obtained from molecular simulations by determining the mean first passage time for the transition from the metastable form to the stable form. Thus, comparing to experiments provide a way to gauge simulation accuracy. Another performance metric, the power output, equals the rotation speed times the average work the motor does in each rotation cycle. However, the power output depends on factors extrinsic to the motor, notably the magnitude of load and how the load is coupled to the motor. A more general and intrinsic property is the thermodynamic maximum of the work per cycle, which is related to the free energy released when the motor undergoes THI.
