Liquid crystal dimers and higher oligomers: between monomers and polymers
TL;DR: The underlying theme of this Critical Review is the relationship between molecular structure and liquid crystalline behaviour in a class of materials referred to as liquid crystal oligomers, and how this molecular architecture has been exploited to address issues in a range of quite different areas and has given rise to potential applications for these materials.
Journal ArticleDOI
Discotic nematic liquid crystals: science and technology
TL;DR: This critical review deals with the structure of various nematic phases, different discotic cores exhibiting the nematic phase, novel designing and transition temperature engineering principles, alignment and physical properties, and the application of discotic nematic LCs as the active switching component and as optical compensation films for widening the viewing angle and contrast ratio of liquid-crystal display devices.

Liquid Crystal Dimers
TL;DR: A comprehensive overview of the relationships between molecular structure and liquid crystallinity in dimers is provided in this article, including a description of the novel modulated and intercalated smectic phases exhibited by dimers.
Journal ArticleDOI
Discotic liquid crystals. A brief review
TL;DR: In this paper, the authors summarized the progress in the field of discotic liquid crystals, with emphasis on experimental results rather than theoretical developments, including metallo-mesogens and discotic polymers.

Plenary Lecture. One hundred years of liquid-crystal chemistry: Thermotropic liquid crystals with conventional and unconventional molecular structure
TL;DR: In this article, the roots of the chemistry of conventional rod-like liquid crystals are briefly considered and low-molecular-weight liquid crystals were analyzed in terms of rigid groups (rod-like and disc-like ring systems), flexible groups, polar groups and short, linking segments.

TL;DR: In this article, the detailed structures of the various discotic phases and some of their important physical properties are described. But they are classified into two distinct categories, the columnar and the nematic.
