nematic

The results showed that M1 and M2 present the enantiotropic nematic phase,M3 presents the nematic phase with SA,SC and SB smectic phases and M4 presents the nematic phase with SA,SC and SB monotropic phases.

研究表明,单体M1和M2呈现互变向列相,M3呈现向列相和近晶A(SA)相、近晶C(SC)相和近晶B(SB)相,M4呈现向列相和单变SA相、SC相和SB相;聚合物P1和P2呈现向列相,P3和P4呈现SA相和向列相。

In this paper, the advantages of these compounds are summarized, showing that naphthalene derivative is useful for preparing a liquid crystal composition with a wide temperature range of nematic phase, very large dielectric anisotropy and a small birefringence, thereby being driven at a low voltage, and suitable for high performance STN.

大量文献数据表明其可加宽混合液晶的向列相温度范围;增大介电各向异性;降低阈值电压以及调节适宜的双折射率,适用于超扭曲向列型(STN型),薄膜晶体管型(TFT型)等高性能液晶材料。

Typical textures of S_C, S_B, S_A and nematic phase were observed.

在液晶态可观察到部分单体的近晶C相(SC)、近晶B相(SB)、近晶A相(SA)和所有单体向列相的典型织构。

The result shows that molecules with non-alkyloxy substituent are nematogenic and short alkyloxy chains (n= 1～3 ) in the homologue lead to nematic phase with odd-even effect, the molecules with longer alkyloxy chains (n=4～1.

当Y为非烷氧基时,呈向列相液晶;当Y为较短的烷氧基时(n=1～3),液晶化合物具有向列相(N);Y为较长烷氧基时(n=4～16),液晶化合物只有近晶B相(SB)和近晶A相(SA);SA-I相变的熵变随烷氧链原子数而奇-偶变化,但与N-I相变的“奇-偶效应”相反。
