Temperature Dependence of Physical Constants with Varied Molecular Length and Position of Fluorine Substituents in Phenyl-bicyclohexane Core Liquid Crystals
TL;DR: In this article, the effects of substitutions of fluorine substituents on physical properties of phenyl bicyclohexane liquid crystals (LCs) were investigated. But the results indicated that substitutions only caused minor differences.

Mechanical Model of Rotation Frame for Phase Stability and Molecular Conformation in Liquid Crystal System
TL;DR: In this paper, a model that explains the phase behaviors and thermal properties of a liquid crystal (LC) system is developed, based on the architecture of a frame consisting of atomic nuclei, and it is shown that the thermal stability of the LC molecules is dominated by the rotational dynamics of the nuclei frame.

Mechanical Rotor Model for Fluorinated Terphenyl Liquid Crystals
TL;DR: In this article, a micro-machine system consisting of an ensemble of molecular rotors was established to explain phase behaviors and thermal properties of liquid crystals (LCs), and the phenomena of the thermal stability of phase and polymorphism are interpreted in terms of mechanics that involve basic parameters such as center of gravity (G), moment of inertia (IA), eccentricity (e), and mass deviation along the molecular axis (δ).

A Mechanical Model Study on Correlations of Liquid Crystal Phase and Dynamic Parameters in Linear Molecules
TL;DR: In this article, three groups of linear molecules, one group having a liquid crystal (LC) phase and two groups having a general state, were prepared to investigate by a mechanical LC system model, the dynamic parameters, the moment of inertia and rotational critical velocity, were calculated to correlate with the appearance of the LC phase.
