PhD Studentship - Imido-Tungstate Photonic Materials: New Molecular Light Switches and Photosensitizers (FIELDENJ_U18SCI)

University of East Anglia - Chemistry

Start Date: October 2018

No. of positions available: 1

Supervisor: Dr John Fielden

Project description:

Nothing travels faster than light, and we have no greater source of energy than the light produced by the sun. Therefore, materials that can manipulate light are vital to future telecommunications and computing technology,(i) as well as meeting our energy demands. Our group is working to develop new materials based on polyoxometalates (POMs, molecular, nanoscale multimetallic coordination clusters),(ii) which exploit POM redox properties to switch optical and photophysical properties, or convert light into chemical or electrical energy.

This PhD project will explore the synthesis, photophysical and photochemical properties of arylimido-polyoxotungstates, aiming to discover (i) materials whose optical and non-linear optical (NLO) properties can be switched by a redox stimulus; and (ii) materials capable of acting as photosensitisers and electron relays for solar energy conversion. The project builds on our work with their molybdate analogues, which we have shown to be both very efficient NLO materials (enabling manipulation of laser light),(iii,iv) and modifiers that increase photovoltages from p-type dye-sensitised solar cells.(v) We expect the tungstates to open new applications in redox-switched NLO or fluoresence/luminescence, owing to their greater stability, and also to be more effective in solar energy applications due to their higher redox potentials.

The successful applicant will gain training in molecular inorganic and organic synthesis, characterisation, and physical measurement of molecular and materials properties. Based in the well-equipped, interdisciplinary Energy Materials Laboratory at UEA, it also involves collaboration with leading international groups. They will also have, or expect to obtain a first class, 2(i) or equivalent Honours degree in chemistry, along with a strong interest in synthetic inorganic chemistry and materials properties. Please contact Dr John Fielden (, 01603 593137) for further information.

Interviews will be held w/c 22 January 2018.

Person specification:

Acceptable first degree: Chemistry. Will also consider chemical physics or biochemistry provided the candidate has acquired adequate inorganic chemistry and synthetic chemistry knowledge during their degree.

The standard minimum entry requirement is 2:1.

Funding notes:

This PhD project is in a Faculty of Science competition for funded studentships. These studentships are funded for 3 years and comprise home/EU fees, an annual stipend of £14,553 and £1,000 per annum to support research training.  Overseas applicants may apply but they are required to fund the difference between home/EU and overseas tuition fees (in 2017/18 the difference is £13,805 for the Schools of CHE, PHA & MTH (Engineering), and £10,605 for CMP & MTH but fees are subject to an annual increase)
