Description
Hiroyuki Matsukizono and colleagues present 2026 unevenly F-bearing phenyl 4-biphenylcarboxylate motifs as a design principle for both-way FE liquid crystals. Knowing small structures that show FE liquid crystal phases during both heating and cooling steps, namely both-way phases, remains a big challenge. Nine analogs based on a fluorinated phenyl backbone are designed, and their FE liquid crystal traits are tested. Of these, eight analogs exhibit both-way FE liquid crystal phases.
One analog with the 2-F unit and a cyano end group exhibits a both-way FE nematic phase at 119 to 190 degrees Celsius. In contrast, analogs using a 2,6-diF unit show weakened or absent FE properties, whereas adding a cyano end group leads to a both-way nematic phase. Quantum math suggests that planar aim of the 2-F unit well promotes between-molecule links in parallel layouts rather than opposite ones, thereby holding FE liquid crystal phases steady.
