Liquid crystals exhibit ferroelectric nematic phase with potential for advanced device applications, indicating significant findings.

This research aims to explore the design and synthesis of new fluorinated liquid crystals with ferroelectric nematic properties.
Synthesis of three novel NF phase compounds
Characterization using polarizing optical microscopy and X-ray measurements
Dielectric and birefringence analyses for assessing phase transitions and molecular ordering.
Compounds exhibit saturated spontaneous polarization comparable to solid-state ferroelectrics
Two compounds show direct Iso-to-NF phase transition and a monotropic NF phase below 30 °C
Large increase in order parameter observed at Iso-NF transition.
