Description

technical field [0001] The invention relates to a thienylpyrrole compound, a preparation method, a polymer prepared by using the same, a preparation method and an application of the polymer. Background technique [0002] The real start to study the electrochemical properties of thienopyrrole derivatives began in 2000. Enric Brillas et al. studied the electrochemical behavior of 2,5-dithienylpyrrole on a Pt electrode; Chane-Ching, L.Toppare and A.Cihaner etc. began to synthesize a large number of new thienopyrrole derivatives, and studied their photoelectrochemical properties in detail. [0003] At present, a large number of polythiophene and polypyrrole derivatives reported in the literature are obtained by chemical oxidation or electrochemical oxidation. However, while oxidizing thiophene and pyrrole monomers, it will lead to peroxidation of the polymer itself, although it can be To prevent this phenomenon by lowering the oxidation potential or strictly controlling the amo...
