Development of emergent ferroelectric nematic liquid crystals with highly fluorinated and rigid mesogens

Abstract

The emerging ferroelectric nematic liquid crystals have been attracting broader interests in new liquid crystal physics and their unique material properties. One big challenge for the ferroelectric nematic researches is...

The effect of a lateral alkyloxy chain on the ferroelectric nematic phase

“…Indeed, the N F phase is arguably the hottest topic in the science and technology of liquid crystals, elevating Born’s work from the status of a footnote. 8–23…”

A new order of liquids: polar order in nematic liquid crystals

“…28,[31][32][33] Green and red arrows indicate increased and decreased T NF-N relative to the parent material, respectively, while a black dash indicates the absence of the N F phase. 39 As with all N F materials known to date, these materials feature polar groups (in this case, 1,3-dioxane, 2,5difluorophenyl, nitrile) oriented in such a way to give a large longitudinal molecular electric dipole moment. Although the high melting points of these materials render them somewhat impractical, the development of a new class of N F materials is nonetheless extremely welcome.…”

A New Order of Liquids: Polar Order in Nematic Liquid Crystals

“…37 Recently, Huang et al have reported two highly fluorinated rod-like mesogens which exhibit the NF phase (Figure 6b). 38 As with all NF materials known to date, these materials feature polar groups (in this case, 1,3-dioxane, 2,5-difluorophenyl, nitrile) oriented in such a way to give a large longitudinal molecular electric dipole moment. Although the high melting points of these materials render them somewhat impractical, the development of a new class of NF materials is nonetheless extremely welcome.…”
