제목 Self-Assembly of Rod-Disc Liquid Crystals and Biaxial Molecular Arrangements under an Electric Field
초록 A series of new molecular discs (RDn) was synthesized via the chemical attachment of six cyanobiphenyl calamitic (rod) mesogens (R) linked to the triphenyl discotic (disc) mesogen (D) with a series of six alkyl chain linkages (n = 6-12). DSC, POM, 1D/2D WAXD, and SAED allowed us to identify three ordered phases below the isotropization temperature and molecular packings in their ordered phases. Both triphenyl discotic mesogens and cyanobiphenyl calamitic mesogens are completely interdigitated. Especially, RD12 exhibits a biaxial N molecular orientation under a DC electric field.
