PB20 Highly ordered liquid crystal phases by intermolecular hydrogen bonding

Abstract

We prepared novel liquid crystalline compounds which have an amide group in the mesogen and a m-substituted alkoxy chain. These compounds were expected to have highly orderd liquid crystal phases by the intermolecular hydrogen bonding. We investigated behaviors of these compounds by polarized light optical microscopy, differential scanning calorimetry, and single crystal and powder X-ray diffractions. In addition, to investigate the effects of the amide linkage and the m-substituent, a diester compound and a p-substituted compound were prepared as the homologs.
