  Mesogenic materials with anomalous birefringence dispersion and high

  摘要：

  这项发明提供了作为电光器件中双折射材料有用的LC组合物，其具有零或低负斜率双折射色散（例如，表现出明显低于当前可用LC组合物的正双折射色散）或更理想的是具有正斜率双折射色散，其中材料的双折射随波长增加而增加。该发明提供了作为LC组合物组分有用的化合物，这些化合物表现出负双折射，其中n.sub.o高于n.sub.e。本发明的化合物是LC类似化合物的二聚体，其中单体通过高双折射基团（二聚体连接剂）连接在一起。LC单体由LC核和一个或两个尾基组成。本发明的首选单体与连接单体的双折射相比具有较低的双折射。二聚体具有正常的正双折射色散，即在较长波长处绝对值较低的双折射。但由于它们具有负双折射，随着波长的增加，它们的双折射实际上会增加（即变得更少负）。

  This invention provides LC compositions useful as birefringent materials in electrooptic devices which exhibit zero or low negatively sloped birefringence dispersioon (e.g., exhibiting positive birefringence dispersion significantly lower than that of currently available LC compositions) or more preferably positively sloped birefringence dispersion in which birefringence of the material increases with wavelength. The invention provides compounds useful as components of LC compositions which exhibit negative birefringence where n0 is higher than ne. The compounds of this invention are dimers of LC-like compounds in which the monomers are linked to each other through a high birefringence moiety (dimerization linker). The LC monomers consist of an LC core and one or two tail groups. Preferred monomers for this invention have low birefringence in comparison to the birefringence of the monomer linking moiety. The dimers have normal positive birefringence dispersion to have birefringence that is lower in absolute value at longer wavelengths. But since they have negative birefringence, their birefringence actually increases (i.e., goes less negative) as wavelength increases.

  A new series of chiral materials, hexy](2s)-2-(6-(-4-(4'-alkoxyphenyl)benz propionates (HmPBNP; m = 6-18) had been prepared and their liquid crystalline properties were investigated as a function of alkyl chain length. These chiral materials exhibited novel ferroelectric S-c* and antiferroelectric Sc-A* phases and a propensity to the formation of the Sc-A* phase was found at longer alkyl chain lengths (m = 10, 12-18). An odd-even effect of the threshold voltage as a function of alkyl chain length for compounds HmPBNP (m = 12-16) possessing antiferroelectricity was observed. Spontaneous polarization and trans verse dipole moment were also measured and are discussed in terms of the elongated alkyl chain length.
