Preparation of Two-dimensional Conjugated Polymer Membranes at Liquid-liquid Interface Based on Oxidative Dehydrogenation Coupling Reaction
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 concentrat-ed 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.
