英文摘要	A series of symmetrically thiophene-based bent-shaped molecules with branched terminal was synthesised and characterised. Then, their effects as dopants on the blue phase (BP) range of the chiral nematic liquid crystal (NLC) host were investigated. It was found that the bent-shaped dopants with branched terminal had better miscibility in LC host than the bent-shaped dopants with straight terminal, and contributed to induce BP and enhance the BP temperature range, with the maximum BP temperature range about 20.4 degrees C. Besides, the electro-optical (E-O) performances of the blue phase liquid crystal doped with Th-BC6 (a bent-shaped dopant with the widest induced BP range in NLC) were also explored. It was found that the drive voltage reduced first and then increased with the doping amount of Th-BC6 increasing. When the doping amount of Th-BC6 was about 15wt%, the hysteresis could be strikingly reduced.; Major Project of International Cooperation of the Ministry of Science and Technology [2013DFB50340]; National Natural Science Foundation of China [61370048, 51333001, 51173017, 51203011, 51103010]; Fundamental Research Funds for the Central Universities [FRF-TP-14-013A2]; SCI(E); ARTICLE; hewanli@mater.ustb.edu.cn; Yanghuai@pku.edu.cn; 4; 524-534; 43
