  The reactivity of a number of chloroarenes was investigated and chloro–nitroarenes were found to undergo facile arylation with Pd(PPh₃)₄ / [Pd(PPh₃)₂Cl₂/n·PPh₃] as catalyst. Furthermore, 4–chlorobenzaldehyde underwent arylation under the conditions, albeit with a higher catalyst loading.

  研究人员对多种氯代烯烃的反应活性进行了调查，发现氯代硝基烯烃在 Pd(PPh3)4 / [Pd(PPh3)2Cl2/n-Ph3] 催化剂的作用下可发生简单的芳基化反应。此外，4-氯苯甲醛也在该条件下发生了芳基化反应，尽管催化剂负载量较高。

  The present invention relates to materials used for aligning liquid crystals of liquid crystal display elements and to a polymer for use in liquid crystal vertical alignment layer used in producing a liquid crystal vertical alignment layer. The polymer for use in a liquid crystal vertical alignment layer includes (a) a moiety that is photochemically isomerizable but not photochemically crosslinked, (b) a moiety that is photochemically crosslinkable, and (c) a moiety that stabilizes a vertical alignment. The polymer can be used to produce a vertical alignment layer that has a liquid crystal alignment property enabling control of alignment at a low UV dose and that offers a large pretilt angle and superior optical stability.

  本发明涉及用于对齐液晶显示元件的材料，以及用于制造液晶垂直对齐层的液晶垂直对齐层聚合物。用于液晶垂直对齐层的聚合物包括（a）具有光化学异构性但不具有光化学交联的基团，（b）具有光化学交联性的基团，以及（c）稳定垂直对齐的基团。该聚合物可用于制造具有液晶对齐性能的垂直对齐层，使得在低紫外线剂量下能够控制对齐，并提供大的预倾角和优异的光学稳定性。
