摘要

本論文包含兩個研究主題， 第一部分在描述在主鏈上含有2,4-methoxytriphenylamine 基團之新穎芳香族聚醯胺之合成與性質。一種新型含三苯胺結構的二胺單體 4,4’-diamino-2”,4”-dimethoxytriphenylamine (2) 是在氟化銫共存下由 2,4’-dimethoxylaniline 和4-fluoronitrobenzene 進行芳香親核取代反應，然後再以聯胺和鈀觸媒催化還原二硝基中間產物而製得。具有 2,4-methoxytriphenylamine 基團之非晶型及有機可溶性之聚醯胺是由芳香族或是脂肪族二羧酸和上述所合成出之二胺以Yamazaki直接進行磷酸化聚縮合反應而製得。

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 ℃.
