Molecular and Nanoscale Rotary Devices Derived from Luminescent Metal-Organic Components
DescriptionA molecular rotor is composed of mobile ('rotator' or 'paddle') and static ('stator') components with small and large moments of inertia respectively. The underlying aim of this project is to design and prepare new molecular rotary devices incorporating suitable environment-sensitive luminescent metal-organic rotator units with different degrees of rotational freedom. This project involves fundamental research for a variety of conceptually different luminescent rotary devices, and the development of new optical strategies to control and signal their molecular movement.The development of functional photoluminescent materials and supramolecular systems that are responsive to changes in their local environments and can report molecular-level information (motion or process) using visible light is desirable, because highly sensitive and often diagnostic spectroscopic techniques that can probe these changes are available. Furthermore, it is becoming apparent that the use of light stimulus to operate molecular devices can be superior to chemical and electrochemical inputs. Investigations probing the relationship between motion (molecular rotation) and light energy (luminescence/excited state properties) in these systems will be undertaken, and this can pave the route for the developments of applications in luminescent molecular 'machines' and functional nanostructures.
