基于异烟酸酯类衍生物的超分子盘状液晶构建

Abstract

As a proton acceptor,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.
