This study investigates the impact of solvent environment on the quantum efficiency of a 2-stroke photon-only molecular rotary motor using multiscale nonadiabatic molecular dynamics simulations. Results show a significant decrease in isomerization quantum efficiency in methanol solution compared to the gas phase, attributed to hydrogen bonding between the motor and solvent molecules. Analysis suggests that modifying the motor to reduce hydrogen bonding could improve quantum efficiency, providing new design rules for light-driven rotary motors.
