WebDiazonium compound. Benzenediazonium cation. Diazonium compounds or diazonium salts are a group of organic compounds sharing a common functional group [R−N+≡N]X− where R can be any organic group, such as an alkyl or an aryl, and X is an inorganic or organic anion, such as a halide . WebTo make use of that property, GCE was used as substrate for electropolymerization of the perfluorinated aniline monomer in acidic solution using cyclic voltammetric scanning. By combining glassy carbon with in-situ polymerized ECP, we intend to eliminate water layer formation. This will result in a highly stable and reliable sensor.
