    2021
    Co-Authors: Saha Rony, Nepal Pawan, Feng Chenrun, Hossein, Md Sakhawat, Gleeson, James T., Sprunt Samuel, Twieg, Robert J., Jakli Antal
    Abstract:

    Ferroelectric nematic liquid crystals represent not only interesting fundamental science, but they also hold promise for storage capacitors with high power Density or new information display technology having sub-millisecond switching. In this work we describe the synthesis and Measurements of the physical properties of a new highly polar ferroelectric nematic compound, 4-nitrophenyl 4-[(2,4-dimethoxylbenzoyl)oxy]-2-fluorobenzoate (RT11001). The dipole moment of this material (along the long molecular axis) is calculated to exceed 11.5 Debye. We employ a wide range of physical characterization methods including differential scanning calorimetry (DSC), mass Density Measurement, Optical birefringence, polarizing Optical microscopy (POM), electric current analysis, and electro-Optical switching, to show that RT11001 has three distinct ferroelectric states, F1, F2 and F3. F1 is purely orientationally ordered ferroelectric nematic phase (NF), F2 has a ferroelectric nematic with possibly short-range hexagonal order normal to the director (NhF), and we conjecture that F3 has a long-range hexagonal order normal to the director (ColhF).Comment: 31 pages, 10 figure
