smectic mesophase

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.

此外,端基柔性较好的化合物倾向于形成近晶相。

The results showed that they all had a smectic phase and some of them had a chiral smectic C phase (Sc*) near room temperature.

液晶性质测试结果表明它们都是近晶相液晶，有些还有多相性。

Polarized light microscopy and differential scanning calorimetry reveal DNC 18DCl3T and DNC 18DI3T exhibit smectic A phase, whereas DNC 8DCl3T and DNC 8DI3T do not form liquid crystal phase.

差示扫描量热法以及偏光显微镜观察结果显示 ,DNC18DCl3T和DNC18DI3T具有液晶性 ,形成近晶A相液晶。
