Experimental Evidence Concerning Two Different Kinds of Smectic C to Smectic A Transitions
TLDR
In this article, experimental evidence is presented indicating that there are two distinctly different kinds of smectic C-to-smectic A transitions: first order with zero tilt and second order with non-zero tilt angle in both phases.Abstract:
Experimental evidence is presented indicating that there are two distinctly different kinds of smectic C to smectic A transitions. The first type is second order with zero tilt in both phases, the second type is first order with a non-zero tilt angle in both phases. The model for the second type of transition is an “uncoupling” of the tilt directions of adjacent layers in the smectic -A phase.read more

Bent-core liquid crystals: polar order, superstructural chirality and spontaneous desymmetrisation in soft matter systems
TL;DR: An overview on the recent developments in the field of liquid crystalline bent-core molecules (so-called banana liquid crystals) is given in this article, dealing with general aspects of the systematisation of the mesophases, development of polar order and chirality in this class of LC systems and explaining some general structure-property relationships.

Ionic Liquid Crystals: Versatile Materials.
TL;DR: The discussion is focused on low molar mass and dendrimeric thermotropic ionic mesogens, as well as selected metal-containing compounds (metallomesogens), but some references to polymeric and/or lyotropic ionIC liquid crystals and particularly to ionic liquids will also be provided.

Antiferroelectric chiral smectic liquid crystals
TL;DR: In this paper, the authors have suggested the pair formation of transverse dipole moments in adjacent smectic layers as the cause of antiferroelectricity in liquid crystals.

Current topics in smectic liquid crystal research.
TL;DR: This Review discusses some of the topics of highest interest in current smectic liquid crystal research, and address application-relevant research (de Vries-type tilting transitions without defect generation and high-tilt antiferroelectric liquid crystals with perfect dark state) as well as more curiosity-driven research.

Why the Molecules are Tilted in all Smectic A Phases, and How the Layer Thickness Can be Used to Measure Orientational Disorder*
TL;DR: The concept of inherent tilt inherent to all A phases accounts for the observed differences between layer thickness d and molecular length l of four quite different compounds, without any need for assuming additional tilt, interdigitation, or kinking of chains.

Temperature-dependent tilt angle in the smectic C phase of a liquid crystal
TL;DR: In this article, the authors used conoscopic observation and circularly polarized light to estimate the C phase temperature dependent tilt angle of liquid crystal smectic C-particle tilt angle.
