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.
本文介绍了一种用于偏光色谱和特别是二向色染料的修饰剂,其中链接基包含至少四个线性连接的原子间隔链,该链在一端与液晶基团耦合,另一端可连接到非离子染料色团以形成修饰的二向色染料。本文还介绍了这种修饰染料化合物以及它们在客体-宿主组成物和含有染料化合物的器件中的使用。
