Summary on Grant Application Form |

The purpose of this programme is to exploit the unique qualities of novel smectic liquid crystal materials which we invented for applications in microdisplays, projectors, very fast spatial light modulators for photonic switching, optical correlators, electrooptical neural networks, optical computing applications and novel display systems. Our fundamental research in the area of ferroelectric and antiferroelectric LCs yielded a number of materials incorporating microphase segregating units - coded as the CDRRn materials, which gave us access to systems that could be aligned into monodomains, where the monodomains are electro-optically bistable. Such stable bistable states, that do not relax into chevron structures, are ideal for device applications. If the states are destroyed, for example by thermal or mechanical shock, then the bistable monodomain structure can be restored using only conventional drive voltages, thus the bistability is robust and secure. If these properties can be better understood and reproduced in ferroelectric liquid crystal device mixtures it would remove possibly the main impediment to the wider commercial exploitation of FLC devices. Thus, in this proposed programme we plan to synthesise a larger number of materials based on the CDRRn family of compounds, and to prepare them in substantial quantities so that they can be employed in the device work of Cambridge University (Prof Crossland) and various UK and USA companies.
