  An object of the present invention is to provide an efficient method of manufacturing 3,3′,4,4′-tetraaminobiphenyl with a smaller number of steps. The manufacturing method of 3,3′,4,4′-tetraaminobiphenyl includes reacting the amino groups of a 4-halo-o-phenylenediamine with an inorganic sulfur compound to lead to a 5-halo-2,1,3-benzothiadiazole, subsequently coupling two molecules of the benzothiadiazole together to form a 5,5′-bis(2,1,3-benzothiadiazole) and then deprotecting the amino groups to yield 3,3′,4,4′-tetraaminobiphenyl.

  本发明的目的是提供一种更少步骤的高效制备3,3′,4,4′-四氨基联苯的方法。该制备方法包括将4-卤基-o-苯二胺的氨基基团与无机硫化合物反应，形成5-卤基-2,1,3-苯并噻二唑，随后将两个苯并噻二唑分子耦合在一起形成5,5′-双(2,1,3-苯并噻二唑)，然后去保护氨基基团以得到3,3′,4,4′-四氨基联苯。

  Disclosed is a fluorine-containing dicarboxylic acid represented by formula (1), wherein n represents an integer of 1-4, and the two carboxylic groups are not adjacent to each other on the aromatic ring. It is possible to obtain a linear polymer compound by reacting the fluorine-containing dicarboxylic acid with a comonomer (e.g., diaminodiol). By thermal cyclization, this linear polymer compound can be converted into another polymer compound having superior characteristics.

  本发明公开了一种含氟的二羧酸，其化学式表示为（1），其中n表示1-4的整数，两个羧基不相邻于芳环上。通过将含氟二羧酸与共聚单体（例如，二氨基二醇）反应，可以获得线性聚合物化合物。通过热环化，这种线性聚合物化合物可以转化为具有优异特性的另一种聚合物化合物。
