  The Molecular Structures and Properties of Anthraquinone-Type Dichroic Dyes

  摘要：

  Relations between the molecular structures and properties of anthraquinone-type dichroic dyes were studied. Newly developed asymmetric dyes with thiophenyl groups are highly soluble in fluorinated liquid crystals and the dichroic ratios of these dyes are high (about 10). However, ortho-position (thiophenyl)-substituted dyes have lower solubilities and dichroic ratios than other position-substituted dyes. The properties of anthraquinone dyes with anilino groups are much lower than those of dyes with thiophenyl groups. These results can be strongly related to the flexibility of substituents. We newly established a hypothesis concerning dyes in liquid crystal solvent. In liquid crystals, the dye has a suitable conformation to adjust to liquid crystal phase. In this conformation, the solubilities and dichroic ratios are increased because the interactions between the dye molecules and liquid crystal molecules are strengthened. Flexible substituents are considered to easily form a suitable conformation and realize excellent properties.

  The present invention relates to LED lighting elements comprising translucent mouldings composed of polycarbonate-based moulding compounds, comprising a colourant mixture, carbon black, scattering additive and optionally white pigment, as used, for example, as covers with a day/night design. Through combination with one or more RGB-LEDs, it is possible to achieve surprising colour effects in night design with presence of a deep gloss effect in mouldings that are black and grey in day design.
