LIQUID CRYSTAL COUPLED DICHROIC DYES
Modifiers for pleochroic, and in particular dichroic, dyes in which a linking group contains a spacing chain of at least four linearly linked atoms that is coupled at one end to a liquid crystal moiety and is connectable at the other end to a nonionic dye chromophore to a nonionic dye to form a modi...

Summary: | Modifiers for pleochroic, and in particular dichroic, dyes in which a linking group contains a spacing chain of at least four linearly linked atoms that is coupled at one end to a liquid crystal moiety and is connectable at the other end to a nonionic dye chromophore to a nonionic dye to form a modified dichroic dye, to such modified dye compounds, and to their use in guest-host compositions and devices containing the dye compounds, are disclosed. |
