摘要：Three kinds of bent-shaped molecules (A-1, A-2, A-3) were synthesized and doped into the chiral nematic host to induce blue phase. The widest induced blue phase temperature range of 48.6 degrees C is gained for the molecules with acrylate end groups and lateral substituent CN, which has the largest biaxiality and better solubility. After ultraviolet (UV) irradiation, the blue phase range was reduced to 39.1 degrees C, the relationship between the molecular structures and the inducing effect was discussed.
