Summary

The influence of electrolyte and monomer concentration on properties and morphology of electrochemically obtained polyselenophene films doped and undoped with hexafluorophosphate and tetrafluoroborate anions was analyzed. The films were deposited on SnO2-coated glass in a classical three-electrode cell from the monomer and the electrolyte in anhydrous acetonitrile.

The electrochemical growth of polyselenophene thin films was studied by X-ray photoelectron spectroscopy (XPS), electron probe microanalysis (EPMA), and scanning electron microscopy (SEM). The morphology study revealed different three- dimensional (3D) and bidimensional (2D) growth, depending on monomer and electrolyte concentration.
