ABSTRACT
The work presents a study on the optical absorption anisotropy (linear dichroism) of the p-p* absorption band of a series of azodyes. The azodyes have been oriented in the nematic liquid crystal 4-cyanophenyl-4’-pentyl benzoate. The linear dichroism of the dye molecules in the nematic matrix is also evaluated as function of the temperature.
