TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Condensate: The partial-hydrolysis condensate is preferably obtained by carrying out partial-hydrolysis condensation of the novel compound in the presence of another silicon compound capable of carrying out hydrolysis condensation.Preferred Film: The thin film contains hole in the film. SPECIFIC COMPOUNDS - 16 examples for the fluorine-containing aromatic group-having compound of formula (1), such as compounds of formulae e.g. (4-1), (4-5), (4-9) and (4-16), are disclosed.    EXAMPLE - Decafluoro biphenyl (in g) (20.05) was dissolved in tetrahydrofuran (100 ml). The obtained solution was mixed with 1 mol/l lithium phenyl acetylide tetrahydrofuran solution (150 ml) and stirred violently. The stirring was continued for 8 hours, and the reaction solution was mixed with 0.1 N hydrochloric acid (2 l). The solution was precipitated, filtered and recovered. The recovered solid was water-washed and vacuum-dried at 50degreesC for 2 hours to obtain a crude product. The obtained crude product was subjected to sublimation purification at 180degreesC, to obtain fine yellow crystals (25) of 4,4'-bis(phenyl ethynyl) octafluorobiphenyl. The obtained crystal (7.32), triethoxy silane (9.84), tetrahydrofuran (80) and 3% platinum divinyl tetrasiloxane complex toluene solution (20 mul), were mixed. The obtained mixture was maintained at 75degreesC for 8 hours by heating on an oil bath, and cooled to room temperature. Tetrahydrofuran and excess triethoxy silane were removed by evaporation, and oil-like substance (12.1) was obtained. The obtained oil-like substance was the novel compound having a structure (formula (12)). The obtained novel compound (4.13), propylene-glycol-monomethyl-ether acetate (41.3) and tetraethoxy silane (1.04) were mixed. The obtained mixture was mixed with 0.7 mass% maleic acid aqueous solution (0.81) and stirred violently at room temperature. The stirred mixture was heated at 60degreesC for 5 hours and concentrated to obtain partial-hydrolysis condensate solution composition (22.1). The solid content of the obtained composition was 15 mass%. The obtained composition was filtered and spin-coated on a silicon wafer. The coated composition was baked in nitrogen atmosphere, to form a thin film of thickness 500 nm. The dielectric constant and elasticity of the obtained film were 2.6 and 8 GPa, respectively.
