TLDR
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.Abstract:
Interest in the smectic liquid-crystalline state of matter received a substantial boost with the discovery by Meyer in the mid-1970s that a chiral smectic C (SmC*) phase exhibits a spontaneous electric polarization, and with the subsequent demonstration by Clark and Lagerwall of the surface-stabilized SmC* ferroelectric liquid crystal at the beginning of the 1980s. Since then, chiral smectic phases and their plethora of polar effects have dominated the research in this field, which today has reached a mature state where the first commercial microdisplay applications are now shipping in millions-per-year quantities. In this Review we discuss 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 (the nature and origin of the chiral smectic C subphases and their intermediate frustrated states between ferro- and antiferroelectricity).read more

A new era for liquid crystal research: Applications of liquid crystals in soft matter nano-, bio- and microtechnology
Jan P. F. Lagerwall,Giusy Scalia +1 more
TL;DR: In this paper, the authors review the physics aspects of the new research thrusts, in which liquid crystals often meet other types of soft condensed matter, such as polymers and colloidal nano- or microparticle dispersions.
Journal ArticleDOI
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.
Journal ArticleDOI
Carbon nanotubes in liquid crystals
TL;DR: A review of the literature on carbon nanotube (CNT) dispersion in liquid crystals (LCs), focusing mainly on the approaches where the aim is to align CNTs along the LC director field, but also covering briefly the proposed possibility to enhance thermotropic LCs by CNT doping.
