3,3'-Diamino-N,N'-[perfluoropropane-2,2-diylbis(6-hydroxy-3,1-phenylene)]dibenzamide

개요2,2-Bis(3-(3-aminobenzoylamino)-4-hydroxyphenyl)hexafluoropropane (m-6FDAP) 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.
