When liquid crystal molecules are chiral, the twisted structure competes with spatially uniform liquid crystalline orders, resulting in a variety of modulated liquid crystal phases, such as the cholesteric blue phase, twist grain boundary and smectic blue phases. Here we report a liquid crystal smectic blue phase (SmBPiso), formed from a two-component mixture containing a chiral monomer and a ‘twin’ containing two repeat units of the first molecule connected by a linear hydrocarbon spacer.

Liquid Crystalline Blue Phases
Blue phases are known to appear in chiral liquid crystals in a small temperature range between the chiral nematic phase and the isotropic one. They are optically active, non-birefringent, and they
Achiral flexible liquid crystal trimers exhibiting gyroid-like surfaces in chiral conglomerate phases.
TLDR
Both surface and bulk structures of a homologues series of an achiral liquid crystal trimer I-(n,m) exhibiting soft crystalline chiral conglomerate phases are investigated by atomic force microscopy and scanning electron microscopy to form bicontinuous networks exhibiting optical activity.

TLDR
An electrically induced anisotropic birefringent structure in the chiral isotropic phase and a photoinduced 3D-3D phase transition in the smectic Q phase are introduced as possible application on the basis of the frustrated chiral 3D structured liquid crystal phases.
Stable Amorphous Blue Phase of Bent-Core Nematic Liquid Crystals Doped with a Chiral Material
We report an induction of the blue phase III (BPIII) at a relatively low and wide (over 20 °C) temperature range in nematogenic achiral bent-core liquid crystals doped with a high twisting power
Nano-Structure and Dynamics of Isotropic Order 1
Liquid state has highest symmetry, so the X-ray diffraction pattern is completely uniform and symmetric in the space. Thus, space has complete spherical isotropic symmetry in liquid state. On the

We fabricated, in a polymer matrix, liquid crystal (LC) nanosized droplets with a correlation length ξ of about 140 nm, which appear as an optically isotropic film. Differential scanning calorimetry
Polymer-stabilized blue phases: promising mesophases for a new generation of liquid crystal displays†
Blue phases—special chiral liquid crystalline mesophases—are promising candidates for electro-optic devices with improved performance and simplified fabrication. A necessary precondition for possible
Study of Liquid Crystals Showing Two Isotropic Phases by 1H NMR Diffusometry and 1H NMR Relaxometry
In this work, we report a study of two thermotropic liquid crystalline samples showing a not common mesophase behavior. The samples, namely a di-benzyloxy biphenyl derivative labelled 9/2 RS/RS, and
Super-structured smectics and their application
Super-structures produced in the smectic molecular organization are reviewed, and the origin for the structures discussed, in which it is emphasized that the frustration plays an important role in
Pre-organized liquid crystals: biaxial nature of laterally-connected dimer
Biaxial nematic liquid crystals have attracted much attention from both fundamental and application points of view, because the fast response based on the rotation of the minor director is expected.

Transparent nematic phase in a liquid-crystal-based microemulsion
TLDR
This work replaces the oil component of a conventional water-in-oil microemulsion with an intrinsically anisotropic fluid—a nematic liquid crystal that is an ordered nematic at the mesoscopic level, but which does not exhibit the strong light scattering generally associated with bulk nematic order.
Chirality in liquid crystals
Chirality has become arguably the most important and complex topic of research in liquid crystals today. The reduced symmetry in these organized phases leads to a variety of novel phase structures,
