Abstract
X-ray photoelectron spectroscopy (XPS) studies were performed on conductive polypyrrole-tetrafluoro-p-benzoquinone (PPY-p-fluoranil), polypyrrole-tetrachloro-p-benzoquinone (PPY-p-chloranil) and polypyrrole-tstrabromo-o-benzoquinone (PPY-o-bromanil) complexes prepared via the simultaneous chemical polymerization and oxidation of pyrrole by the respective acceptor. In all complexes, XPS data suggested the presence of negatively charged oxygen, the halogen anion and the positively charged pyrrolylium nitrogen. More extensive charge transfer interaction in the complexes is associated with higher electrical conductivity. However, the charge transfer interactions in each complex may have proceeded further than the pure formation of molecular complex.
