Characterising Molecular Self-Assembly by Solid-State NMR
Supervisor: Steven P. Brown (Physics)
Co-Supervisor: Andrew Marsh (Chemistry)
A pre-requisite for the design of smart materials is the characterisation of molecular structure and dynamics with atomic resolution. There are many important cases where the systems to be investigated lack the periodic order necessary for characterisation by X-ray diffraction. By contrast, nuclear magnetic resonance (NMR) is a probe of the local environment of the atomic nuclei and is thus well suited for application to systems lacking periodic order.
This project uses advanced solid-state NMR methods (including at the UK 850 MHz Solid-State NMR Facility that is based at Warwick) in a multi-disciplinary project linking physics to chemistry. The specific focus is to gain new insight into the specific three-dimensional packing arrangements exhibited by organic molecules, where it is important to understand the competing roles of different intermolecular interactions, e.g., hydrogen bonding and CH- interactions. In supramolecular chemistry, synthetic guanosine derivatives exhibit a rich self-assembly with potential applications in molecular electronics, ion extraction and as biomimetic ion channels. This project will involve interaction with collaborators in the USA (Davis group, University of Maryland) and in Italy (Masiero group, University of Bologna) that builds upon publications in high impact journals (Webber et al., J. Am. Chem. Soc. 133, 19777, 2011; Peters et al, J. Am. Chem. Soc. 136, 12596, 2014; Peters et al, J. Am. Chem. Soc. 137, 5819, 2015).
