    • The present invention relates to compounds represented by the following Formula Ic, in which R2-R6 can each independently be selected from hydrogen or hydrocarbyl (e.g., methyl); L1 and L4 are each independently a divalent linking group, such as a bond or —OC(O)—R8—C(O)O—, where R8 can be divalent hydrocarbyl (e.g., —CH2CH2—); each L2 and each L5 each independently represent a flexible segment, such as divalent linear or branched C1-C25 alkyl; each L3 and each L6 each independently represent a rigid segment including, for example, optionally substituted phenylen-1,4-diyl groups; t and s are each independently from 1 to 4; m and p are each independently from 0 to 4 for each t, provided that the sum of m and p is at least 1 for each t; q and r are each independently from 0 to 4 for each s, provided that the sum of q and r is at least 1 for each s; and E1 and E2 can each independently be hydrogen or hydrocarbyl. The present invention also relates to compositions, such as liquid crystal compositions, and articles, such as optical elements, that include the compound represented by Formula Ic.
    • 本发明涉及由下式Ic表示的化合物,其中R 2 -R 6各自独立地选自氢或烃基(例如甲基); L 1和L 4各自独立地是二价连接基团,例如键或-OC(O)-R 8 -C(O)O-,其中R 8可以是二价烃基(例如-CH 2 CH 2 - )。 每个L 2和每个L 5各自独立地表示柔性链段,例如二价直链或支链C 1 -C 25烷基; 每个L3和每个L6各自独立地表示包括例如任选取代的苯基-1,4-二基的刚性链段; t和s各自独立地为1至4; 对于每个t,m和p各自独立地为0至4,条件是对于每个t,m和p之和至少为1; q和r各自各自为0至4,条件是每个s的q和r之和至少为1; E1和E2各自独立地为氢或烃基。 本发明还涉及包含式Ic表示的化合物的组合物,例如液晶组合物和诸如光学元件的制品。

    • The present invention relates to compounds represented by the following Formula Ia, in which each R1-R6 can in each case be independently selected from hydrogen or hydrocarbyl (e.g., methyl); R7 is a multivalent linking group, such as L1 is a divalent linking group, such as a bond or divalent optionally substituted hydrocarbyl; each L2 independently represents a flexible segment, such as divalent linear or branched C1-C25 alkyl; each L3 independently represents a rigid segment including, for example, optionally substituted phenylen-1,4-diyl groups; t is from 1 to 4; m and p are each independently from 0 to 4 for each t, provided that the sum of m and p is at least 1 for each t; and E can be hydrogen or optionally substituted hydrocarbyl. The present invention also relates to compositions, such as liquid crystal compositions, and articles, such as optical elements, that include the compound represented by Formula Ia.
    • 本发明涉及由下式Ia表示的化合物,其中每个R 1 -R 6可各自独立地选自氢或烃基(例如甲基); R7是多价连接基团,例如L1是二价连接基团,例如键或二价任选取代的烃基; 每个L2独立地表示柔性链段,例如二价直链或支链C 1 -C 25烷基; 每个L3独立地表示包括例如任选取代的亚苯基-1,4-二基的刚性链段; t为1〜4; 对于每个t,m和p各自独立地为0至4,条件是对于每个t,m和p之和至少为1; 并且E可以是氢或任选取代的烃基。 本发明还涉及包括由式Ia表示的化合物的组合物,例如液晶组合物和诸如光学元件的制品。
