The invention relates to a triazole bending rodlike liquid crystal compound and a preparation method thereof, and belongs to the technical field of the liquid crystal compound. The preparation method for the compound comprises a click chemistry reaction, a reaction for eliminating trimethyl silicon, a Sonogashira coupling reaction, etc. The triazole liquid crystal compound prepared by the invention has electron-withdrawing groups and electron-donating groups on end groups of a molecular and has a relatively wide temperature range. Thickness of a displayer can be reduced effectively, corresponding rate can be increased and photoelectric anisotropy of the liquid crystal can be improved when the triazole liquid crystal compound is used for display. Furthermore, the compound is an excellent liquid crystal molecular orientation material, spatial light control material, PDLC thin film material and monomer material for light storage polymerization.
