PB11 Synthesis and mesomorphic properties of 1, 3-diazaazulenoids (2)

Abstract

We have usually studied preparation and mesomorphic properties of troponoid liquid crystals because troponoid cores have large dipole moment to induce smectic phases. Recently, we reported liquid crystals with a 1,3-diazaazulene core, which has larger dipole moment (4.0 D) than tropolone. They showed highly-ordered smectic phases. In this study, we measured X-ray diffraction data of the oriented sample to determine the phases.
