为了通过引入侧向全氟芳烃与芳烃相互作用实现直棒状分子的双轴中间相,非烷基化棒状液晶化合物C 6 X 5 –COO–C 6 Z 4 –C 6 Z 4 –OOC–C 6 Y 5,F-BB-F(X = Y = F,Z = H),F-BB-B(X = F,Y = Z = H),B-BB-B(X = Y = Z = H),B-FF-B(X = Y = H,Z = F),F-FF-B(X = F,Y = H,Z = F)和F-FF-F制备了(X = Y = Z = F),并通过偏光光学显微镜(POM)和差示扫描量热法(DSC)研究了它们的相变行为。通过对F-BB-F的向列相和近晶相A进行一维和二维X射线衍射(1D和2D-XRD)研究,可以清楚地看出,近晶相A在相中具有横向方向顺序。层和向列相具有近晶A近晶结构。
