Electrochemical, optical and vibrational properties of two oligomeric model compounds of emeraldine salt (ES), the only electrically conducting form of polyaniline, in nonaqueous solution are studied. The phenyl-end-capped dimer and tetramer of leucoemeraldine base are electrochemically oxidized in acetonitrile solution and the electrogenerated species are investigated using spectrophotometry and...
The emeraldine salt structure, the only conducting form of polyaniline is not well-known. This is why, we have carried out resonance Raman spectra (RRS) on one of these models compounds oxidized electrochemically in-situ in order to elucidate the electronic structure of this polymer partially oxidized in an acidic medium. A phenyl end-capped dimer of polyaniline, N,N′ diphenyl-p-phenylenediamine (named...
