  • Abstract This thesis consists of two parts. The first part deals with the syntheses and characterization of novel aromatic poly(amine-amide)s bearing a 2,4-dimethoxytriphenylamine unit in the main chain. A new triphenylamine-containing diamine monomer, 4,4’-diamino-2”,4”-dimethoxytriphenylamine was synthesized via the cesium fluoride-mediated N,N-diarylation of 2,4’-dimethoxylaniline with 4-fluoronitrobenzene, followed by palladium-catalyzed hydrazine reduction of the dinitro intermediate. Amorphous and organosoluble poly(amine-amide)s were prepared by the phosphorylation polyamidation of the newly synthesized diamine monomer with various aromatic or aliphatic dicarboxylic acids. All poly(amine-amide)s were readily in organic solvents and could be solution cast into flexible and tough films. All the polymers showed high glass-transition temperatures (Tg) between 243 ℃ and 289 ℃, and they were fairly stable up to a temperature above 500 ℃.
