NEW MATERIAL:A compound shown by the formula I (R is 1W15C alkyl, alkoxy, or alkoxymethyl; ring A and B are cyclohexyl, phenyl, etc.; l is 1, or 2). n EXAMPLE: 4-(Trans-4-propylcyclohexyl)benzoic acic azide. n USE: A liquid crystal composition. Having improv compatibility with biphenyl crystal, ester crystal, Shiff crystal, etc., having a wide liquid crystal temperature range. Since the compound shown by the formula I has low viscosity, a liquid crystal composition using the compound shown by theformula I lowers viscosity. n PREPARATION: A carboxylic acid chloride shown by the formula II is reacted with an aqueous solution of sodium azide in an organic solvent (e.g., acetone, or dioxane) to give a compound shown by the formula I. n COPYRIGHT: (C)1986,JPO&Japio |
