The design and investigation of the self-assembly of dimers with two nematic phases

Description | the project is formally completed, however the collaborations between the teams is still ongoing. high birefringent materials and mixtures are supplied to the collaborating teams. High dielectric anisotropy materials and mixtures have been supplied in line with the work plan. On the way we have established a much better understanding of the twist bend nematic phase, The collaborating engineering teams have used our materials to design and construct new devices. In a number of collaborative publications the fast switching behaviour in flexoelectric properties focused devices was demonstrated. Furthermore, in collaboration with the project partners a number of prototype devices were constructed based on the materials synthesized by us; the focus being on fast switching 2pi flexo-electric light modulators. |
Exploitation Route | The collaborators in Oxford and Cambridge have constructed new devices and reported this in the literature; currently the work on the project is ongoing funded by other sources. We have provided and reported materials design and design rules which advances the field and can be used by others. Further collaborations (industry and academia) are planned. to exploit the results. |

Title | CD spectrometry to investigate spontaneous chirality formation in liquid crystals |
Description | The station B23 at Diamond Light Source Ltd. permits the collection of data in thin films where sample are positioned horizontally. This is critical as flow induced by gravity in vertically positioned films is avoided. Together with temperature control of macroscopically aligned films this permits the recording of signal related to the formation of chiral superstructures in non-chiral molecules. |
