This thesis is focused on the design and synthesis of liquid crystal gold nanoparticles and all of the relevant molecular sub-structures.

In particular it is focused on the optimisation of the synthesis of nematic mesogens with thiolated functional groups. The synthesis of gold nanoparticles in the size regime of 2.0 – 3.5 nm, either functionalised with hydrocarbon or deuterated hydrocarbon groups was achieved. The attachment of the thiolated functionalised mesogens to the gold particles was explored and a series of materials characterised in detail by using transmission electron microscopy (TEM) and gel permeation chromatography (GPC). A particular focus was on the purification methods in order to obtain pure and very well characterised gold nanoparticles (AuNPs) systems. Clear protocols for the preparation of high quality liquid crystal gold nanoparticles (LC AuNPs) were developed. Methods were explored to obtain liquid crystal optical polarised microscopy textures and the liquid crystal behaviour was determined by using DSC studies.

In a collaborative effort, the 2D and 3D structures of these materials were determined and the plasmonic properties characterised, showing that this novel class of materials exhibit synergistic optical properties based on the interaction of both the hydrocarbon groups and the AuNPs.

Overall, significant new knowledge has been added to the field of LC gold nanocomposites.
