In the past quarter century, inherently conducting polymers have attracted great attention due to their important academic interest and industrial applications. Electrochemical polymerization has been proved to be one of the most useful approaches for conducting polymer synthesis with several advantages. Boron trifluoride diethyl etherate (BFEE) solution is a middle strong Lewis acid together with good ionic conductivity and good electrocatalytic properties. When BFEE is used as the solvent, no supporting electrolyte is needed. The complexation of aromatic monomers such as thiophene and its derivatives, benzene, pyrrole, furan, fused ring aromatic compounds, with BFEE can significantly lower the anodic oxidation potentials of the monomers, which is beneficial to the preparation of high quality conducting polymers. For this sake, many efforts have been focused on the electrochemical polymerization during the past decade in pure BFEE and its mixed electrolytes with strong acids such as trifluoroacetic acid or concentrated sulfuric acid, diethyl ether, alcohol or acetonitrile. Up to now, a series of high quality inherently conducting polymers have been produced from these media. In this paper, the electrochemical polymerization of high quality conducting polymers prepared from BFEE and its mixed electrolytes were briefly introduced.
