A fluorinated diamine intermediate

For the preparation of polyimides in application of membranes, capacitors, and photonics


2,2-Bis(3-(3-aminobenzoylamino)-4-hydroxyphenyl)hexafluoropropane (m-6FDAP), derived from hexafluorodiphenylpropane, is end-capped by two anilines with two pedant hydroxy groups. The amide linkers between the hexafluorodiphenylpropane and the anilines undergo a thermal rearrangement with the adjacent hydroxy groups to form benzoxazoles at 425 °C in nitrogen. The polyimides based on 2,2-Bis(3-(3-aminobenzoylamino)-4-hydroxyphenyl)hexafluoropropane become more rigid and thermally stable and they are used for water permeable membranes.

A core-shell nanocomposite of BaTiO3 and m-6FDAP based polyimides exhibits a discharge energy of 23.1 J/cm3 and charge-discharge efficiency of 65% with promising application in capacitors for energy storage.

The pendant hydroxy groups allow lateral functionalization through Mitsunobu reaction to synthesize grafted polyimides. The quinoline grafted polyimides show nonlinear optical performances with second-harmonic generation coefficient of 15 pm/V (at 635 nm) and electro-optic coefficient of 6 pm/V (at 1300 nm).
