Abstract:

Calamitic (rod-shaped) and discotic (disc-shaped) thermotropic liquid crystalline (LC) compounds were spread at the air-water interface, and their ability to form monolayers was studied. The calamitic LCs investigated were found to form monolayers which behave analogously to conventional amphiphiles such as fatty acids. The spreading of the discotic LCs produced monolayers as well, but with a behaviour different from classical amphiphiles. The areas occupied per molecule are too small to allow the contact of all hydrophilic groups with the water surface and the packing of all hydrophobic chain

Significant progress has been made in recent years in modelling liquid crystal phases using the Monte Carlo and molecular dynamics simulation techniques. We describe the technique of molecular dynamics in the microcanonical ensemble that we have used in simulations of liquid crystal systems. A review and discussion of some of the important simulations that have been performed to date on non-spherical hard particle models, soft anisotropic single site models, and realistic atom-atom based models is presented. We report the results of molecular dynamics simulation studies of a system of particle

Abstract:

This thesis is concerned with the self-organization of molecules that have disc-like shapes. The disc-like molecules may have relatively rigid structures as in polyaromatic systems, or they may have amphiphilic structures with polyaromatics at their cores, and soft outer shells made up of aliphatic chains. This research seeks to explore molecular compatibility and the ensuing structures formed by such disc- like systems through the study of phase diagrams. Thus, the thermodynamic behaviour and miscibilities of discotic liquid crystal materials were investigated by the formation of Gibbs phase

Abstract:

Discotic liquid crystal research is now more than 30 years old, however it is still early days compared with the well-established area of calamitic liquid crystal research which dates back for more than a century. Since the 1990’s there has been great deal of interest in discotic liquid crystal research, due to applications such as discotic compensation films for enhancing liquid crystal display (LCD) viewing angles and exciting new potential applications such as organic semi-conductors and photovoltaics.The work contained in this thesis can be broken down into three major areas: investigation

Abstract:

The alignment of liquid crystal (LC) materials at surfaces is important for many applications such as those in the display industry and chemical and biological sensors. The alignment of thermotropic calamitic LC is an interesting field of research and has been studied well. However, little has been done in the area of discotic liquid crystals in general and in the field of the lyotropic discotic liquid crystal in particular. Discotic liquid crystals have gained interest recently due to their electrical conduction in one dimension, which makes them potentially useful for electronic devices such

Unsymmetrical compounds based on hexa-n-alkoxy triphenylenes were also examined. A number of techniques were employed to observe and measure the physical properties of these compounds.

Abstract:

This thesis presents a detailed investigation of the relationship that exists between the molecular structure and the mesomorphic behaviour in discotic liquid crystals. This was achieved by the systematic alteration of the molecular architecture of one class of discotic liquid crystals - the triphenylen-2,3,6,7,10,11-hexayl hexakis(4-alkoxybenzoate)s which were first studied in 1981. It was shown, by the systematic increase in the lateral substituents (from hydrogen through to tert-butyl, both mono- and di-substituted) in both the outer and inner regions of the peripheral phenyl rings of these

The work described in this thesis (Chapter 2) concerns the synthesis of macrodiscotic structures which led to the formation novel discotic liquid crystalline systems.
