A study is presented on the control of rotary motion an appending rotor unit in a light-driven molecular motor. Two new light driven motors were synthesized that contain aryl groups connected to stereogenic centers. The behave as bidirectional free rotors three four isomers 360° rotation cycle, but hindered fourth isomer. Kinetic studies both motor and functions two compounds are given, using (1)H NMR, 2D-EXSY UV-vis spectroscopy. In addition, we present development method for introducing range substituents at α-carbon precursors motors. shows how system can be photochemically switched between state reveals dynamics coupled systems.
