Supramolecular Discotic Liquid Crystals Formed by Hydrogen Bonding of Isonicotinic Acid Derivatives
rod-like isonicotinic acid derivatives could form hydrogen bonds with symmetrical disc-like core phloroglucinol and obtain a supramolecular discotic liquid crystal structure. Temperature dependent FT-IR was used to study the thermal stability of the complexes at the aid of DSC and POM
and the phase structures were confirmed by using X-ray diffraction technique. The results show that the ester-linked bond can reduce the order degree of H-bonded system and induce discotic nematic liquid crystals.
