提出了一条合成苯胺齐聚物的新路线 :由高氧化态的苯胺四聚体与二苯胺或 N-苯基 - 1,4 -对苯二胺反应合成苯基封端的苯胺五聚体和六聚体 ,用红外、质谱、核磁共振、基底辅助激光解吸质谱 (MAL DI- MS)进行了表征 .提出一条可能的机理 ,即高氧化态的苯胺四聚体与二苯胺或N -苯基 - 1,4 -对苯二胺在酸性溶液中混合时 ,四聚体、二苯胺和 N -苯基 - 1,4 -对苯二胺的分子中均形成阳离子自由基 ,四聚体的阳离子自由基与后二者的阳离子自由基耦合形成苯胺五聚体和六聚体 .还原态的苯胺齐聚物氧化成中间氧化态的苯胺齐聚物 ,使用硫酸铵和六水和三氯化铁等氧化剂能打断苯胺五聚体和六聚体的分子链 .实验发现 ,氧化银是将还原态苯胺齐聚物氧化成中间氧化态的齐聚物的最好的氧化剂 .用紫外可见光谱对中间氧化态的五聚体和六聚体进行了研究 ,对其分子中醌环的数目进行了讨论 A new route for the synthesis of aniline oligomers was proposed: the phenyl-terminated aniline pentamers and the hexa-amines were synthesized from the reaction of the aniline tetramer of high oxidation state with diphenylamine or N-phenyl-1,4-p-phenylenediamine (MALDI-MS) was characterized by infrared spectroscopy, mass spectrometry, nuclear magnetic resonance, and a possible mechanism was proposed, that is, aniline tetramer with high oxidation state and diphenylamine or N-phenyl- When the 1,4-phenylenediamine is mixed in an acid solution, the tetramers, diphenylamines and N-phenyl-1,4-p-phenylenediamines form cationic radicals in the molecules, and the tetramers have free cations The radical and the latter two are coupled to form an aniline pentamer and a hexamer. The aniline oligomer in the reduced state is oxidized to an aniline oligomer in an intermediate oxidation state using ammonium sulfate, hexahydrate and ferric chloride Oxidants can interrupt the molecular chain of pentamers and hexamers of aniline.It is found that silver oxide is the best oxidant for the oxidation of reduced aniline oligomers to oligomers in the intermediate oxidation state.Using UV- The oxidation states of pentamers and hexamers were studied in their molecules by quinone rings The number of discussions
