Reaction Steps
The monomer 4,4'-bis(1-naphthoxy)octafluorobiphenyl (8FNE) was prepared by the following procedure. A 100 mL round bottom flask was charged with decafluorobiphenyl (3.01 g, 0.0090 mole), 1-naphthol (2.60 g, 0.0181 mole), potassium carbonate (2.95 g, 0.0218 mole), and DMAc (40 g). The mixture was heated with stirring at about 140° C. for 2 hr and then cooled to room temperature, filtered, and poured into toluene (100 mL). The toluene solution was washed with 5% sodium hydroxide (50 mL) and then twice with deionized water (2×100 mL). After drying with magnesium sulfate and filtering, it was concentrated by rotary evaporation to yield a red solid. The solid was recrystallized from DMAc/water, filtered, and dried to yield 8FNE (3.9 g, 78.8% yield; m.p. 189°-191 ° C.; GC/MS m+ /e 582).
