Synthesis and Mesomorphism of A Novel Triphenylene-based Discotic Liquid Crystal with Chiral Chain Mingxia Zhang,Yifei Wang, Chunxiu Zhanga,Hao Wu and Jialing Pub Information recording materials Lab,Beijing Key Laboratory of Printing & Packaging Materials and Technology, Beijing Institute of Graphic Communication, Beijing 102600, China azhangchunxiu@bigc.edu.cn,bpujialing@bigc.edu.cn Keywords: Triphenylene; Chiral liquid crystals; Column; Discotic Abstract.
Triphenylene-based discogens are among the most intensively studied discotic liquid crystalline materials, as their synthetic methodologies have been well developed and high purity compounds can be prepared through column chromatography and recrystallization[3].
Materials synthesizes in this study are shown in Fig.1 and are described as follows.
