摘　　要：以5,10-二氢-5,10-二甲基吩嗪和吩噻嗪为单体,在三氯化铁+浓硫酸、过硫酸钾、高锰酸钾、高锰酸钾+浓硫酸等四种不同催化剂存在的条件下,探究其是否能进行自身氧化脱氢偶联反应,并且在液液界面上合成二维共轭聚合膜。该反应具有操作简单、反应条件温和等特点。对于反应产物二维共轭聚合膜,利用光学显微镜及扫描电子显微镜对其表面形貌进行了表征,并进一步通过红外光谱、X射线光电子能谱和X射线衍射仪表征其结构特征。In this work,5,10-dimethyl-5,10-dihydrophenazine and phenothiazine were used as monomers to explore whether they could perform self oxidative dehydrogenation coupling reaction and synthesize two-dimensional conjugate polymer membranes on the liquid-liquid interface in the presence of four different catalysts:ferric chloride and concentrated sulfuric acid,potassium persulfate,potassium permanganate,potassium permanganate and concentrated sulfuric acid.This reaction has the characteristics of simple operation and mild reaction conditions.For the two-dimensional conjugate polymer membranes,its surface morphology was characterized using optical microscopy and scanning electron microscopy,and its structural characteristics were further characterized by infrared spectroscopy,X-ray photoelectron spectroscopy and X-ray diffraction.
