A mechanical model study on correlations of liquid crystal phase and dynamic parameters in linear molecules

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. The analysis of the molecular dynamic parameters allows the assessment of why these molecules behave differently in the formation of phase.
