実験手順: To a 250 ml 3 neck round bottom was added 9-Hydroxyfluorene (5 g, 0.027 mole, 1.0 equivalent), 2-methyltetrahydrofuran (50 g), triethylamine (3.3 g, 0.03 mole, 1.2 equivalents) and cooled in an ice bath. The cooled solution was treated with acryloyl chloride (2.7 g, 0.03 mole, 1.1 equivalents) dropwise over 1 hour. Analysis by gas chromatography indicated 60/40 mixture. The reaction was washed two times with sodium chloride brine (25 ml, 20% aqueous solution), concentrated invacuo to recover a solid. The material was dissolved in chloroform (50 ml) and added to a silica gel column containing 500 g silica gel and eluted with hexane/ethyl acetate at varying concentrations of 1-2.5% (ethyl acetate). The product was eluted first and was recovered by concentrating invacuo. Recovered 2.5 g of a pale yellow oil, which quickly solidified, having a melting point of 64-65 C. Polymerizable Resin Composition 1: 40 parts of FA-1 (with a refractive index of 1.613), 50 parts CN120 (epoxy acrylate available from Sartomer Company, Exton, Pa., reported by Sartomer to have a viscosity of 2150 cps at 65° C., a refractive index of 1.5556 and a Tg of 60° C.), 10 parts SR339(2-phenoxyethyl acrylate available form Sartomer), and 0.3 parts Darocur 4265 (available from Ciba Specialty Chemicals, Tarrytown, N.Y.) were mixed together thoroughly in an amber jar. Optical Film Sample Preparation: Brightness enhancing films samples were made using Polymerizable Resin Composition 1. About 3 grams of warm resin was applied to a 2 mil primed PET (polyester) film, available from DuPont under the trade designation “Melinex 623” and placed against a microstructured tool with a 90/24 pattern similar to the commercially available Vikuiti TBEF-90/24. The PET, resin and tool were passed through a heated laminator set at approximately 150° F. to create a uniformly thick sample. The tool containing the film and coated resin sample was passed at 50 fpm through a Fusion UV processor containing two 600 W/in D-bulbs. The PET and cured resin were removed from the tool and cut into samples.

実験手順: To a cold (0° C.) suspension of 9-hydroxyfluorene (49 g) in benzene (650 mL) was added thionylchloride (70 mL). This solution was allowed to stir while warming up to room temperature overnight. The benzene was distilled off and the product was recrystallized from isopropylether to give 41 g of the title compound as a white solid: m.p. 87°-89° C. The benzene was distilled off the product was recrystallized from isopropylether

実験手順: To a 250 mL round-bottomed flask was added 9-hydroxyfluorene (5 g, 27.4 mmol) and triethylamine (3.86 ml, 27.4 mmol) in benzene (150 mL) to give a colorless solution. The solution was cooled to 8° C. with an ice bath. Next, acryloyl chloride (2.229 mL, 27.4 mmol) was dissolved in 25 mL of benzene, placed in a dropping funnel, and added over 1 hour with vigorous stirring. The reaction formed a white precipitate. The ice bath was removed and the viscous sludge was stirred overnight at room temperature. The resulting cloudy white suspension was washed with 50 mL water, followed by 50 mL 5% NaOH solution, and 50 mL water. The benzene layer was collected and dried with MgSO4, filtered, and rotovapped to give the 9-fluorenylacrylate as a viscous beige oil which crystallized on cooling to 4° C.
