摘要： It is an object of the present invention to provide fluorinated bis(phthalic anhydride) which has less coloration and higher solubility in comparison with conventional compounds, and a method for producing the same. Further, it is also an object of the present invention to provide a method for producing a fluorinated bis(phthalonitrile) compound, which is an intermediate raw material compound of the method for producing the fluorinated bis(phthalic anhydride), and a polyamic acid and a polyimide, which are produced from the fluorinated bis(phthalic anhydride). A fluorinated bis(phthalic anhydride) of the present invention is the fluorinated bis(phthalic anhydride) represented by the following formula (I1), wherein its specific surface area is 3.0 m2/g or larger. It is also characterized in that its molar absorption coefficient is 0.6 L/mol·cm or less at a wavelength of 360 nm. [wherein, m and n independently represent integers of 1 to 3, and Z1 represents a single bond group or a bivalent organic group.]
