Helical buckling in columnar assemblies of soft discotic mesogens.

چکیده
We investigate the emergence of chiral meso-structures in one-dimensional fluids consisting of stacked discotic particles and demonstrate that helical undulations are generated spontaneously from internal elastic stresses. The stability of these helical conformations arises from an interplay between long-ranged soft repulsions and nanopore confinement which is naturally present in columnar liquid crystals. Using a simple mean-field theory based on microscopic considerations we identify generic scaling expressions for the typical buckling radius and helical pitch as a function of the density and interaction potential of the constituent particles.

A Monte Carlo study of the chiral columnar organisations of dissymmetric discotic mesogens
We study the relation between the chirality of a discotic mesogen and that of the chiral columnar aggregates that they can spontaneously form by self– assembly. We discuss first the different types of chiral columns that can be in principle obtained. We introduce then a simple two–site Gay–Berne dissymmetric molecular model where chirality can be easily varied and perform extensive NPT Monte Ca...
متن کاملBiaxial Discotic Gay-berne Mesogens and Biaxial Nematics
We investigate the thermotropic liquid crystal phases formed in a system of biaxial discotic mesogenic Gay-Berne particles with strong in-plane interactions when the attractive and repulsive biaxialities have the same or the opposite sign. We find that a biaxial nematic phase is obtained when the shape and well depth anisotropies have the same sign while we do not observe a columnar phase.

Using atomistic molecular dynamics simulations we study solid and liquid crystalline columnar discotic phases formed by alkyl-substituted hexabenzocoronene mesogens. Correlations between the molecular structure, packing, and dynamical properties of these materials are established.

The studies on discotic molecules at air-water (A-W) and air-solid (A-S) interfaces have drawn lot of attention [1, 2]. The thin films of discotic mesogens have technological applications in the fabrication of gas sensors [3], field-effect transistors [4], photovoltaic diodes [5], solar cells and optical displays [6]. In addition, these systems have scientific interest in modeling of Π-Π and st...
متن کاملSequential phase transformation of propeller-like C3-symmetric liquid crystals from a helical to ordered to disordered hexagonal columnar structure.
In this paper, we report thermally induced intercolumnar phase transitions of C3-symmetric liquid crystals (LCs) bearing a triazole-based propeller-like aromatic mesogen. Since the constituting aromatic rings are conjugated through rotatable single bonds, the mesogenic shape is tuneable depending on the degree of conformational motion. Molecule 1 with ninefold octyl peripheries shows a hexagona...
