実験手順

To a mixture of 4"-(n-pentyloxy)- 1,1':4',1"-terphenyl!-4-carboxylic acid (10.5 mmol) and dicyclohexylcarbodiimide (10.5 mmol) in ethyl acetate at 0° C. is added pentafluorophenol (11.5 mmol). The mixture is stirred at 25° C. for a period of 18 h, producing a precipitate. The mixture is filtered. The filtrate is washed with water and brine and dried with magnesium sulfate. The solvent is removed in vacuo to obtain pentafluorophenyl 4"-(n-pentytoxy)- 1,1':4',1"-terphenyl!-4-carboxylate, C30H23F5O3, M.W.=526.5.
