▎ 摘　　要

In this work, halogenated azobenzene and alpha cyclodexterin (CD) are simulated as an axle and a wheel respectively, while the edge carboxylated graphene sheet (ECG) is a stopper. Azobenzene onto CD and combination with ECG can be used such a non-covalent system for photo-isomer-controlled machine. It has been exhibited a new system of molecular motor which works like a hinge motion, and has introduced as light-driven molecular hinges. The CD ring in the system can be reversibly switched through irradiation of wide range of UV and visible lights. Various sensors can be simulated to predict a model for applying the drug delivery of those antibiotics which cannot be used through straight injection.
