Disclosed are bis-meta-benzotrifluoride compounds having the general formula
where each A is independently selected from the group consisting of NO₂, NH₂, and NH₃⁺Z⁻, Z⁻ is an anion, and B is selected from the group consisting of O, CO, S, SO, and SO₂. The diamine compounds are useful as monomers in making polyimides, polyamide-imides, and polyamides.
