TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: Component A of formula (1) is represented by any of formula (X) group. Component A of formula (1) is represented by any of formula (Y) group.R1-R8=H, Cl, F, CN, NO2, or -CF3; andZ=sulfone, hexafluoropropane group, carbonyl group, sulfide group, or ether, provided that sulfide group and ether have electron-attractive group.Preferred Parameters: Light transmittance of polyimide containing repeating unit of formula (3) at wavelength of 400 nm is greater than or equal to 80%, which remains greater than or equal to 75% after exposing to 250 degrees C in atmosphere for 30 minutes. Polyimide containing repeating unit of formula (3) dissolves in aprotic organic solvent by greater than or equal to 5 wt.%. Preparation (Disclosed): An amide group-containing alicyclic tetracarboxylic dianhydride is synthesized by preparing liquid A consists of 1,2,4-cyclohexane tricarboxylic acid-1,2-anhydride-4-chloride and cyclohexanone, preparing liquid B consists of 2,2'-bis(trifluoromethyl)-4,4'-diamino biphenyl, cyclohexanone, and arylglycidyl ether, cooling liquid A while slowly dripping with liquid B, throwing solution in toluene, filtering deposit, washing, and vacuum-drying. Preferred Definitions:    R1-R8=H or -CF3; and    Z=sulfone group.    SPECIFIC COMPOUNDS - 6 Compounds of (1) are specifically disclosed, e.g. formula 4-8.    EXAMPLE - An amide group-containing alicyclic tetracarboxylic dianhydride of formula (4) was obtained by adding 1,2,4-cyclohexane tricarboxylic acid-1,2-anhydride-4-chloride (7.5 g) and cyclohexanone (7.5 g) to a nitrogen-substituted 100 mL 4-neck flask, dissolved, and set as liquid A. The 2,2'-bis(trifluoromethyl)-4,4'-diamino biphenyl (5.3 g), cyclohexanone (26.4 g), and arylglycidyl ether (11.3 g) were added to another container, dissolved, and set as liquid B. Liquid A was cooled to 0-5 degrees C, and liquid B was slowly dripped over liquid A so that the solution would not exceed 5 degrees C. Reaction liquid was thrown into toluene (263 g) after a 4-hour stirring, and deposit was separated by filtration. The deposit was vacuum-dried at 80 degrees C after washing with toluene for 12 hours, and white powder was obtained (56% yield).
