Electrochromic materials in building materials , transportation and electronics industries have great economic significance and ecological value , the application prospect is very considerable . The subject through the comparison of the photochromic materials of electroluminescent , screening of the three target compounds , i.e. three kinds of containing the pyrrole derivative of the the ionene fine structure . Obtained by a detailed study of the synthesis mechanism , the continuous improvement of the synthesis conditions , five new compounds and H ~ 1-NMR, IR, UV-VIS , etc. The structure of the test , to prove its target product . Testing, the use of the electrochemical properties of the cyclic voltammetry couplet pyridyl Pyrroles ionene fine structure proof contained in the monomer structure , its electrochemical properties did not change significantly , the oxidation potential of the pyrrole groups introduced to increase slightly . Couplets pyridyl pyrrole derivative polymerization of the monomers , respectively, using the constant potential polymerization and cyclic scan polymerization . Polymerization conditions were optimized .
