Parsons-Lee and Monte Carlo study of soft repulsive nematogens

Article Abstract:

The nematogenic behavior of prolate thermotropic liquid crystals over a broad temperature range is investigated by employing an approach based on the Parsons-Lee theory for soft repulsive molecular fluids. It is found that the reduction of the effective molecular diameter with temperature in the Kihara soft repulsive fluid implies implicitly an increase of the elongation of the molecules.

Reinvestigation of carrier transport properties in liquid crystalline 2-phenylbenzothiazole derivatives

Article Abstract:

The phase transition behavior and charge carrier transport properties of the 2-phenylbenzothiazole derivatives are reported. They are found to be usual for the smectic A (SmA) phase and the charge mobility in the SmA phase of calamitic liquid crystals is of order of [10.sup.-4][cm.sup.2]/Vs.
