[0093] Synthesis of 2-Cinnamoyloxyethyl Methacrylate (Compound C-8)

[0094] A solution of 8.3 g (0.05 mol) of cinnamoyl chloride and 10 mL of dry dimethylacetamide was slowly added to a stirred solution of 6.5 g (0.05 mol) of 2-hydroxyethyl methacrylate and 14 mL of dry pyridine under cooling in an ice bath middle. When the addition was complete, the cooling bath was removed and the mixture was allowed to warm to ambient temperature over 3 hours. Water and ethyl acetate were added to the reaction mixture and the product was extracted into the organic layer. The organic layer was washed successively with 1N hydrochloric acid solution, saturated sodium bicarbonate solution and saturated sodium chloride solution, then dried over magnesium sulfate, and filtered. The solvent was removed under vacuum to yield 12.1 g (93% of theoretical 13.0 g) of monomer as a clear yellow oil. The composition was verified using NMR. The monomer was...

Abstract

A photosensitive composition is disclosed including a fluorinated photo cross-linkable polymer provided in a fluorinated solvent such as a hydrofluoroether. The photo cross-linkable polymer includes a first repeating unit having a fluorine-containing group but not a cinnamate group, and a second repeating unit having a fluorine-containing cinnamate group. The polymer has a total fluorine content in a range of 30 to 60 % by weight. The composition can be used to form patterned barrier or dielectric structures over substrates and devices such as organic electronic devices.
