Journal ArticleDOI
Liquid crystals of disc-like molecules
TL;DR: Based on the x-ray data, a structure is proposed in which the discs are stacked one on top of the other in columns that constitute a hexagonal arrangement, but the spacing between the discs in each column is irregular as discussed by the authors.
Journal ArticleDOI
The structure and energetics of defects in liquid crystals
S. Chandrasekhar,G. S. Ranganath +1 more
TL;DR: In this article, a systematic account of the structures, energies and interactions of defects in the nematic, smectic, cholesteric and discotic phases of liquid crystals is presented.
Journal ArticleDOI

TL;DR: A "peelable banana" is formed when a bent-core molecule is linked to a rodlike mesogen through a flexible aliphatic spacer in this novel low-molar-mass organic system, which displays a transition from a biaxial nematic (N b ) phase to a bIAxial smectic A phase.
Journal ArticleDOI
A thermotropic biaxial nematic liquid crystal
TL;DR: In this paper, optical studies have been carried out on a nematogenic copper complex, which incorporates the features of both rod-like and disk-like molecules, and conoscopic figures have been presented demonstrating the occurrence of a biaxial nematic phase in the pure complex, the uniaXial-biaxial (Na-Nb) transition in binary mixtures, and the temperature variation of the biaaxiality near this transition.
Journal ArticleDOI
X-ray studies on the columnar structures of discotic liquid crystals
TL;DR: The columnar mesophase as mentioned in this paper is characterized by a structure in which the disc shaped molecules are stacked one on top of the other to form columns, the different columns constituting a two-dimensional lattice.
