<h2 class="heading hide-accessible">Summary</h2>

Nanometre-sized polyhedral or prismatic chemical architectures can self-assemble from combinations of transition metal cations and multifunctional ligands. Likewise supramolecular materials such as coordination polymers or metal-organic frameworks (MOFs) may be formed. These assemblies are often hollow or porous and provide a confined chemical space where other molecules can be bound.<br /> <br /> Hence many of these systems are being developed as nano-scale vessels or crystalline sponges for chemical entrapment, signalling and sensors, and even as tiny reaction vessels. We use the host molecule cyclotriveratrylene (CTV) as a scaffold as its relatively rigid pyramidal shape lends itself to the formation of cage-like or porous species, and analogues with three or six metal-binding groups can be made. These can form discrete metallo-cages, MOFs or other network materials including unique chemical topologies such as a Borromean chain-mail.<br /> <br /> Different potential projects in this area include (i) functional metallo-cages for applications such as molecular recognition, chemical sensors or catalysis; (ii) trinuclear complexes of host ligands with luminescent or catalytic properties; (iii) stimuli-responsive metallo- and organic cages which can change shape or composition with a physical or chemical trigger. All projects include multi-step organic synthesis of ligands, synthetic coordination and supramolecular chemistry, solution characterisation of assemblies and host-guest and other properties using spectroscopic techniques, single crystal X-ray crystallography, and more.<br /> <br /> Keywords: inorganic coordination chemistry, supramolecular chemistry, metal-organic framework<br /> <br /> The earliest start date for this project will be 1 October 2020.

<h2 class="heading">How to apply</h2>

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="">University&rsquo;s website</a>. Please state clearly in the research information section&nbsp;that the research degree you wish to be considered for is &lsquo;Metallosupramolecular assemblies and metal-organic frameworks&rsquo;&nbsp;as well as&nbsp;<a href="">Professor Michaele Hardie</a> as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>

<h2 class="heading heading--sm">Entry requirements</h2>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

<h2 class="heading heading--sm">English language requirements</h2>

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
