1B06 Mesomorphic Properties of Triphenylene Mesogens Possessing Terminal Functional Groups in the Peripheral Chains for Hydrogen-Bond Interaction

Abstract

Some disc-shaped triphenylene derivatives with terminal functional groups at the adjacent two or one long chains were synthesized in order to qualitatively investigate on the correlation between hexagonal columnar mesomorphism and rotational dynamics of molecule around the columnar axis. The effect of intermolecular hydrogen bonding interaction among the terminal functional groups on the Col_h behavior was discussed with some evidences of temperature dependent IR spectra.
