Design of Potentially Photorefractive Liquid Crystalline Materials: Derivatives of 3,6-Disubstituted Carbazole

The incorporation of photorefractive molecular units, such as carbazole, into anisotropic materials
(liquid crystals) may offer many advantages over conventional electrical poling of photorefractive polymers. Thus,
a series of symmetric 3,6-disubstituted carbazole derivatives with a bent molecular shape have been synthesized
and characterized. The influence of the nature of the symmetric substituents on the carbazole is investigated through
comparison of crystal packing and electrostatic potentials.
