摘要：

The spectral and electro-optic properties of some dichroic fluorescent dyes (bicarboxylic acid derivatives) in isotropic solvents and nematic liquid crystal mixture E18 have been studied. In addition, the order parameters of the dyes in the anisotropic matrix and the temperature of the nematic-isotropic phase transition for the dye-liquid crystal mixtures have been determined. It was found that the dyes investigated absorb blue and emit green light, are oriented well in liquid crystalline matrix, have high fluorescence efficiency, are stable to sunlight and do not destabilize the nematic phase of the host. Therefore, they can be utilized in 'guest-host' liquid crystal display devices.
