We synthesized nonpolar rod-like liquid crystalline molecules consisting of hydrogen and carbon atoms. The compound exhibited a novel liquid crystal phase (X phase) between two conventional nematic liquid crystal phases. We investigated the phase transition behaviors and liquid crystallinities by using a polarized light microscope (POM), a differential thermal analysis (DTA), and one- and two-dimensional X-ray diffractometers (1D-XRD and 2D-XRD). In this phase, a first order transition was observed in POM. Additionally, we simulated X phase structures by GROMACS calculation.
