Summary:

Image of Research

Molecules deposited on surfaces can organise themselves into ordered and even complex structures based on intermolecular interactions. This is a process known as two-dimensional supramolecular self-assembly. A variety of Scanning probe microscopy techniques combined with optical spectroscopy can be used to visualise these molecular networks as well as mapping their chemical and optical properties with nanoscale resolution.

The main objectives of this work are to understand how the design of the individual molecular building blocks and the environmental conditions under which self-assembly takes place can be used to control the structures that are formed. These structures will then be used as templates for organising more complex components such as nanoparticles or fluorescent sensor molecules. Being able to accurately control the position of components, especially nanoparticles, in complex 2D structures will open up exciting new possibilities in areas of nanotechnology such as sensors, organic photovoltaic materials and molecular electronics.
