49.9 g of the 4-(4-benzyloxycarbonylphenoxy)nonafluorobiphenyl prepared as described in Example 1 (0.092 mol) and 26.1 g of potassium 4-nitro-3-benzyloxyphenoxide (0.092 mol) are dissolved in 400 ml of dimethylformamide, and the solution is heated to 80° C.; the reaction is complete after 24 hours. The solvent is then removed in a rotary evaporator. The solid residue obtained is washed three times with methanol, filtered off via a Buchner funnel and subsequently dried for 48 hours under nitrogen at 40° C./10 mbar in a vacuum drying cabinet (yield: 94%).
