Description | The prediction of organic molecular crystal structures is a demanding challenge for computational chemistry, and reliable methods in this field will allow computationally-directed design of molecules with targetted solid-state properties. An aim of this project was the development of crystal structure prediction methods that are able to be used on large molecules with intrinsic porosity, to direct the synthesis of new molecules with improved properties. A key early finding in this project is that small changes to large molecules can have a big impact on the entire landscape of possible crystal packings of a molecule, not just on the crystal structure that is observed. For example, one molecule might have only one low enegy possible crystal structure, while a modified version has many nearly energetically equivalent crystal structures available. The former is desirable for engineering predictable crystallisation. A key finding relates to the stabilisation of porous structures by inclusion of solvent of crystallisation. We have been developing computational models for assessing the amount that a particular structure can be stabilised by a given solvent. This allow us to assess which of the possible crystal structures of a molecule will be crystallised under given conditions. This has contributed to our discovery and synthesis of several new porous materials with potential applications for gas storage or molecular separations. |
Exploitation Route | The findings are developing crystal structure prediction methods in general, so could be used in any area where the arrangement of molecules in the solid state has an important impact on properties of interest (pharmaceuticals, pigments, dyes, orgaic electronics). Since the publication of results from this project, several research groups have started using crysta structure prediction methods in their research programmes for functional materials discovery. |

Description | The outcomes of the project have changed the way that structure prediction is used to guide the discovery of new materials. The most far-reaching impact of this research is still within academia, where the methods are being more widely adopted. The results will also create impact outside of academia and may already being doing so: in pharmaceutical materials and chemical industry where the discovery of new materials relies large on experimentation. |
