The purpose of this position is to use single molecule spectroscopy to study the properties of conjugated polymers in solution.  Conjugated polymers are an important class of organic semiconductors which combine novel optoelectronic properties with simple fabrication protocols from solution such as spin coating or ink jet printing. It is known that the conformation of the polymer in solution impacts the optical properties and efficiency of the resulting films and devices but a detailed understanding of polymer conformation in solution and how this influences light emission is still lacking. The University of St Andrews has exceptional research facilities to study the properties of these organic semiconductors, ranging from infrastructure for device fabrication and characterisation to equipment for fundamental studies of light-emitting processes. A postdoctoral fellow position under joint supervision of Dr Carlos Penedo and Prof Ifor Samuel is available immediately in the field of single-molecule spectroscopy of conjugated polymers in solution.

You will apply our existing single molecule measurement facilities to investigate the conformation of single chains of conjugated polymers in solutions and how this influences light emission. Moreover, you will develop hybrid single-molecule techniques combining fluorescence detection with mechanical manipulation of the polymer conformation using magnetic tweezers.

You should hold a PhD in physics and have demonstrated experience in the development of single-molecule instrumentation both for microscopy and spectroscopy applications. Experience in one or more of the following will be a significant advantage: software engineering for equipment control (LabView, C++ or similar), fluorescence microscopy, magnetic tweezers, photophysics of conjugated polymers. Initiative and eagerness to work at the interface between disciplines and to explore new fields of research is essential.

The position is for three years to start as soon as possible.
