  Lateral fluorinated bent-shaped molecules based on a 1,7-naphthalene central core and alkoxy tails can form a switchable hexagonal columnar phase and B4 phase. The columnar phase has a large two-dimensional hexagonal lattice of 65–70 Å and exhibits ferroelectric switching with spontaneous polarization along the column axis.

  We synthesized a novel banana‐shaped molecule based on a 1,7‐naphthalene central core that exhibits a distinct mesomorphism of the nematic‐to‐nematic phase transition. Both the X‐ray profile and direct imaging of atomic force microscopy (AFM) investigations clearly indicates the formation of an anomalous nematic phase possessing a two‐dimensional (2D) tetragonal lattice with a large edge (ca. 59 Å)

  我们基于1,7-萘中心核合成了一种新颖的香蕉状分子，该分子表现出向列相到向列相变的明显同构。X射线轮廓和原子力显微镜（AFM）研究的直接成像都清楚地表明，一个异常向列相的形成具有二维（2D）四方晶格，该晶格具有垂直于晶界的大边缘（约59Å）。低温向列相的导向。一个类似的模型是通过对Skyrmion晶格的提法提出的，在该模型中，由左旋和右旋扭弯螺旋形成的两种圆柱体堆叠成二维四边形晶格，从而减小了反演畴壁。

• Synthesis and mesomorphic properties of bent-shaped molecule with low bent-angle central core and long alkylthio tail

  Two homologous series of bent-shaped molecules composed of low bent-angle naphthalene central core and long alkoxy tail or alkylthio tail, N(1,7)-n-OPIMB and N(1,7)-n-SPIMB (n = 20, 22), respectively, were synthesized. The mesomorphic properties were investigated by differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and X-ray diffraction (XRD). Compared to the direct transition from the isotropic phase to the chiral B4 phase examined in N(1,7)-n-OPIMB, N(1,7)-n-SPIMB exhibited a rare Iso-N-col-Col(h)-B4 phase sequence. The combination of the asymmetric low bent-angle 1,7-naphathalene central core and the flexible long alkylthio tail is considered to play an important role in the formation of such a novel phase sequence.
