Synthesis and Mesomorphic Properties of Achiral and Chiral Esters with High Tilted Synclinic and Anticlinic Phases
摘要:
Two series of three ring esters with chiral chain (derivative of (S)-octanol-2) and achiral chain (the swallow type) with high tilled synclinic and anticlinic phases were chosen to studies. The aim of presented studies was to find how the changes of different molecule units influence the mesomorphic properties of the compounds (temperatures, enthalpies and the sequence of phase transitions) and to find members with the best properties for mixture formulation. The compounds were studied by polarising microscope, differential scanning calorimetry, miscibility and X-ray diffraction methods.
