摘要：NEW MATERIAL:The compound of formula I (ring H is trans-1,4-disubstituted cyclohexane ring; ring A is 1,4-disubstituted phenylene or trans-1,4-disubstituted cyclohexane ring; R1 and R2 are 1-8C alkyl). USE:A liquid crystal electro-optical element. It has high transition temperature from liquid crystal to isotropic liquid, excellent compatibility with other liquid crystal or non-liquid crystal compound and high chemical stability. A voltage margin in multiplex driving can be improved. PREPARATION:The compound of formula I can be produced by chlorinating the compound of formula II with a chlorination agent such as thionyl chloride and reacting the resultant compound of formula III in toluene under refluxing.
