This course builds on the material in the Level 6 Nanophysics (PHYS32600) unit. In this unit, we focus on molecular materials, the link between molecular interactions and nanoscale behaviour, and its exploitation in the fabrication of real devices. Liquid crystals are introduced as an example in which control of intermolecular interactions gives control of physical properties, including mechanical (spider silk) and electro-optic properties (light modulators and displays). The electronic properties of molecules will be examined, with applications in organic transistors and photovoltaic materials. The importance of interfaces in the nanofabrication of materials will also be considered. Many molecular processes take place in solution. We consider solution thermodynamics, the role of the solvent in modifying intermolecular forces, and the origin of Brownian forces and hydrodynamic interactions. Other topics to be discussed include nanostructured stimuli-responsive materials, molecular nanomachines and nano-swimmers.
Aims:
To study nano-structured molecular materials. To show how control at the molecular level can lead to a variety of different structures with applications as broad ranging as cell membranes, photonic crystals, tunable lasers and molecular transistors. To examine self assembly and molecular ordering in liquid crystalline systems and to show how control of molecular architecture and interactions and influence mechanical, thermal and electro-optical behavior. To examine the electronic properties of molecules and applications of semi-conducting polymers in molecular transistors and photovoltaic materials. To examine the influence of surfaces and interfaces in nanofabrication. To show how a solvent affects both the structure and dynamics of a molecular system, and discuss the implications of this for the design of molecular systems such as stimuli-responsive materials and molecular-scale machines.
