Susan Bourne is the Professor of Physical Chemistry at the University of Cape Town, and an Associate Editor of CrystEngComm. Her PhD, obtained at the University of Cape Town, was a study of organic inclusion compounds undertaken under the supervision of Luigi Nassimbeni. After a postdoctoral period in Texas, USA, she joined the Chemistry Department at the University of Cape Town and rose through the ranks to become full Professor in 2008.

Her research interests include the application of physicochemical methods to inclusion compounds and crystal engineering of metal-organic materials, all with the aim of correlating solid state structure with physical properties and reactivity. She has served as Head of Department, Deputy Dean, and as interim Dean of the Faculty of Science at the University of Cape Town. She is a Fellow of the Royal Society of Chemistry and a Fellow of the African Academy of Sciences. She is the author of more than 170 papers in recognized peer-reviewed journals, and 4 book chapters, and regularly participates in national and international conferences, including several introductory and plenary lectures.
In 2019 she received the IUPAC Distinguished Women in Chemistry or Chemical Engineering award. In 2023 she was elected to the executive committee of the International Union of Crystallography.

Lecture summary

Frameworks may be made up of relatively strongly bound entities such as those that make up metal-organic frameworks (MOFs) or may be more loosely bound such as host-guest systems where the host molecules crystallise as independent entities but leave spaces which can accommodate guest molecules. Flexibility can be achieved through the use of non-covalent interactions such as hydrogen- or halogen-bonding. These ‘soft’ interactions allow for reversible processes, allowing the preparation of dynamic materials which respond to their chemical or physical environment. Among the more interesting examples of dynamic processes in frameworks are those which result in thermochromic and/or mechanochromic effects. Materials of this type are particularly of interest if they are able to revert to their original state on application of another external perturbation signal. Rational design of such systems remains a challenge however and is thus an exciting area for application of crystal engineering principles.

In this presentation, examples from recent work in our laboratory will be presented, including MOFs and 3D hydrogen bonded frameworks constructed from the same flexible multitopic ligands.
