Supermolecular liquid crystals

Journal of Materials Chemistry, 2005
In this article we review recent work on the development and study of the properties of self-organising supermolecular and supramolecular materials, that are in size comparable to small proteins. We take the concept of the creation of dendritic liquid crystals, and apply it to the creation of new materials with single identifiable entities, so that ...

Liquid Crystals and Liquid Crystal Solutions Studied By NMR

1999
Abstract Since the first publication on this subject in 1963, {NMR} in liquid crystalline systems has been a wide and active field of research in many branches of chemistry, physics, biology, and materials science. Indeed, thanks to the wealth of exploitable nuclei and interactions, {NMR} spectroscopy has revealed a powerful means of probing structure ...

Carbohydrate liquid crystals

Carbohydrate Polymers, 1984
Abstract Certain alkyl l-O and l-S glycosides with hydrocarbon chain lengths greater than hexyl have been shown to form thermotropic liquid crystals at temperatures between 60 and 100[ddot]C. These are believed to be members of a large class of alkyl and acyl carbohydrate mesogens which, apart from their intrinsic value as potentially useful solid ...

Liquid crystals for magneticians ferroelectric liquid crystals

IEEE Transactions on Magnetics, 1976
The rapid development of research on the physics of liquid crystals in recent years is largely due to the application of knowledge, ideas, and experimental techniques from various aspects of solid state physics to these unusual materials. For those studying phase changes, response to external fields, and defect structures in liquid crystals, analogies ...

LIQUID CRYSTAL MATERIALS AND LIQUID CRYSTAL DISPLAYS

Annual Review of Materials Science, 1997
▪ Abstract  Since the early 1970s, three major prerequisites have brought the success of the liquid crystal display (LCD) technology to its key role of today. Namely, the discovery of electro-optical field-effects on which the displays are based, the successful search for liquid crystals (LCs) with material properties that meet the complex ...

Polymer liquid crystals-liquids or crystals

1993
Liquid crystals belong to a class of materials which were first described over a hundred years ago as characterising a state of matter intermediate between that of a crystal and a liquid. The light microscopic textures which are observed in these “ordered liquids” are very characteristic and have been described in many text books /1/.

Liquid Crystals: Liquid crystal group's inaugural meeting

Physics Bulletin, 1983
On three gloriously warm sunny days, 15–17 September 1982, approximately 80 scientists and engineers met in Southampton to talk about liquid crystals. This was the first meeting of the British Liquid Crystal Group – the newly formed discussion group – and no restrictions were placed on the subjects to be discussed, the only brief being that talks and ...

Liquid Crystals and Liquid Crystal Displays

2014
Liquid crystal displays are used in a wide range of consumer goods, for example, flat panel televisions, smartphones, notebook computers and in-vehicle navigation displays. The development and uses for liquid crystalline materials in electronic displays is described in this chapter, with an emphasis on publications from the patent literature, a primary
