Thermotropic mesomorphism has been observed in pure compounds consisting of simple disc-like molecules, viz., benzene-hexa-n-alkanoates. Thermodynamic, optical and x-ray studies indicate that the mesophase is a highly ordered lamellar type of liquid crystal. Based on the x-ray data, a structure is proposed in which the discs are stacked one on top of the other in columns that constitute a hexagonal arrangement, but the spacing between the discs in each column is irregular. Thus the structure… 
Discotic liquid crystals
Recent studies have established that many compounds composed of disc-shaped molecules exhibit stable thermotropic liquid crystalline phases. They are now referred to as discotic liquid crystals.
Structural features of the hexagonal phase of phasmidic liquid crystals
Abstract Eighteen compounds having the same molecular architecture, a rod-like aromatic core with four to six long aliphatic terminal groups, which all possess a hexagonal mesophase, have been
Macroscopic evidence of molecular chirality in columnar mesophases
Besides the classical liquid crystals observed with rod-like molecules (nematic and smectic mesophases) and plastic crystals obtained in the case of globular compounds, two new classes of
Computer modelling of discotic liquid crystals
The majority of liquid crystals are based on elongated molecules thai form so-called calamitic phases. In the late 1970s liquid crystals based on flat discshaped molecules were first synthesized.
X-ray structural study of the mesophases of some cone-shaped molecules
We have established by X-ray diffraction that cone-shaped molecules can form relatively well ordered columnar mesophases. Four mesophases have been studied. Three of them have the classical
Plenary Lecture. One hundred years of liquid-crystal chemistry: Thermotropic liquid crystals with conventional and unconventional molecular structure
Abstract The roots of the chemistry of conventional rod-like liquid crystals are briefly considered. The low-molecular-weight liquid crystals are analysed in terms of rigid groups (rod-like and
Structure of a disk-like mesophase
We have obtained X-ray diffraction patterns from the mesomorphic phase of two derivatives of terphenylene. The observations agree with the structure already proposed for the mesomorphic phase of a
Crystalline arrangement of some disc like compounds
Three triphenylene esters, disc-like molecules, belonging to a series of compounds, some of which show a new mesomorphic and thermotropic phase have been studied by X-ray diffraction. The crystal
Pressure studies on two discotic liquid crystals
Pressure-temperature diagrams have been studied for two discotic compounds, hexa-n-octyloxytriphenylene and hexa-n-decanoyloxytriphenylene, both of which exhibit the columnar (D) phase at atmospheric
Structures of the Two Discophases of Rufigallol Hexa-n-Octanoate
Abstract X-ray diffraction experiments have been performed on the two mesophases DB and DC of the hexa-n-octanotate of rufigallol (RHO). The disk-like molecules form parallel columns, and the mean
