The present invention provides one or more dichroic dyes which exhibit high solubility in liquid crystal and a high order parameter. The dichroic dyes each have a first substituent having at least one cis-cyclohexane ring and/or a second substituent having at least one trans-cyclohexane ring. The dichroic dye(s) may be provided as a mixture including at least a first dichroic dye having at least the first substituent and a second dichroic dye having at least the second substituent. The dichroic dye(s) may also be provided as a plurality of dichroic dyes, each of the molecules of which has at least the first substituent and the second substituent. The present invention also provides a liquid crystal composition and a liquid crystal element including the one or more dichroic dyes.
本发明提供了一种或多种二色性染料,其在液晶中表现出高溶解度和高序参量。这些二色性染料中,每个都具有至少一个顺式环己烷环的第一取代基和/或至少一个反式环己烷环的第二取代基。这些二色性染料可以作为混合物提供,包括至少一种具有第一取代基的二色性染料和至少一种具有第二取代基的二色性染料。这些二色性染料也可以作为多种二色性染料提供,每个分子都具有至少第一取代基和第二取代基。本发明还提供了一种液晶组合物和一种包括一种或多种二色性染料的液晶元件。
