Paragraph 0061; 0062, (2019/08/18)
The invention discloses a preparation method of a thienopyridine-type ionic rod-like liquid crystal and ionic liquid compound. The thienopyridine-type ionic rod-like liquid crystal and ionic liquid compound have structures as shown in a general formula I, a general formula II and a general formula III. Asymmetric compounds represented by the general formula I show a liquid crystal phase in a certain temperature range, and different inorganic ions and organic ions can be regulated and controlled for carrying out ion exchange. On one hand, storage and release of the inorganic ions and organic ions can be realized in a liquid crystal phase range according to needs; on the other hand, conversion between ionic liquid crystals and ionic liquid is realized through ion regulation and control, anda directional reference is provided for design and application of ion battery materials, special molecular devices and the like. The compounds represented by the general formula II and the general formula III provides another probable design and synthesis idea for the thienopyridine-type rod-like (ion) liquid crystal (plastic crystal) compound. The preparation method is short in route and high inyield.
