Elastic and Optical Properties of Some 4′-n-Alkyl-4-Cyanobiphenyls
P. P. Karat,N. V. Madhusudana +1 more
TL;DR: The bend elastic constants (k 33) and order parameters (S) derived from optical measurements in the nematic phase of pentlyl, hexyl, heptyl and octyl cyanobiphenyls (5CB, 6CB, 7CB and 8CB respectively) are reported in this paper.
Journal ArticleDOI
Elasticity and Orientational Order in Some Cyanobiphenyls: Part IV. Reanalysis of the Data
N. V. Madhusudana,R. Pratibha +1 more
TL;DR: In this paper, the absolute values of the elastic constants and order parameters of several cyanobiphenyls were calculated using the Freedericksz threshold fields and refractive indices.
Journal ArticleDOI
Elasticity and Orientational Order in Some 4′-n-Alkyl-4-Cyanobiphenyls: Part II
P. P. Karat,N. V. Madhusudana +1 more
TL;DR: In this paper, the splay and twist elastic constants of pentyl, hexyl, heptyl and octyl cyanobiphenyls (5CB, 6CB, 7CB and 8CB respectively) have been determined by the Freedericksz transition method.
Journal ArticleDOI
An orientational transition of bent-core molecules in an anisotropic matrix
TL;DR: The detailed phase diagram of mixtures of the two types of compounds revealed the induction of two liquid crystalline phases that are specific to compounds with bent-core molecules, and the chemical nature of the bounding surface had a marked influence on the observed textures.
Journal ArticleDOI
Biaxial smectic A phase in homologous series of compounds composed of highly polar unsymmetrically substituted bent-core molecules
TL;DR: In this paper, a structural model has been proposed for the lower temperature biaxial smectic A phase, which is argued that quartets of molecules, which are conducive to the formation of the BIAxial phase, can form in the layers.
