Importance of liquid crystals used in display
technology has been rapidly increased by technological
developments in recent years. Guest–host liquid crystal
displays (GH-LCDs) are widely utilized because of their
many advantages such as color, wide viewing angle and
high brightness. In this experimental work, azo and
anthraquinone, two differently structured dies (Disperse
Orange11 and 13), were separately doped to two different
nematic liquid crystals (E63 and ZLI-1132). Their solubilities, order parameters, textures and phase transition
temperatures were determined. The highest solubility value
was attained with Orange 13 dye in ZLI-1132 while the
highest order parameter was obtained with Orange 11 dye
in E-63. These dyes did not significantly destabilize the
mesomorphic phase of nematic hosts. It was also observed
that any narrowing on the temperature range of the liquid
crystals had not taken place with the addition of dopants to
the crystal, on the contrary, an increase was recorded.
