A new triphenylamine-containing aromatic diamine monomer, 4-[4-(1-adamantyl)phenoxy]-4',4-diaminotriphenylamine, was synthesized from cesium fluoride-mediated N-arylation of 4-(1-adamantyl)-4'-aminodiphenyl ether with 1-fluoro-4-nitrobenzene and subsequent reduction of the dinitro intermediate.

摘要 本研究首先使用 4-(1-adamantyl)-4'-aminodiphenol ether 与 1-fluoro-4-nitrobenzene，於DMSO中，以氟化铯为媒介，进行氮-芳香化反应（N-arylation），随后再进行中间产物的还原反应，制得一个种新型具有三苯胺结构的芳香族二胺单体 4-[4-(1-adamantyl)- phenoxy]-4'，4-diaminotriphenylamine。
