Functionalization of molecules in confined space

Light-driven molecular motors are unique photoresponsive molecules which can undergo continuous 360 degree unidirectional rotation. However, most of the studies on molecular motors thus far have been conducted in solution and focused on their multi-stage switching behavior. On the other hand, existing reports on photoswitches have revealed that cooperative effects may arise via incorporation into host architectures, which differentiate the assembled systems from simple photoswitching molecules. Aiming to obtain specific functions of motor-based systems, this thesis predominantly focuses on the functionalization of molecular motors into confined space, in aggregates and on particle surfaces. While studying the rotary behavior of motors, we also focus on the cooperative effects that these assembled systems generate. In addition, in these systems, we have made initial attempts to utilize the dynamic rotary motion of molecular motors to perform work.
