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.
基于1,7-萘中心核心和烷氧基尾的侧氟化弯曲形分子可以形成可切换的六角柱相和B4相。该柱相具有65-70 Å的大二维六角晶格,并在柱轴方向上表现出自发极化的铁电开关特性。
