Abstract

Electrochemical polymerisation of 3‐octylpyrrole (OCPY) was studied. Its conductivity was 5 S/cm at an optimal current density of 0.5 mA/cm^2^. Cyclic voltammograms of poly(3‐octylpyrrole) (POCPY) films were measured in the presence of various electrolytes and their shapes were virtually independent of the electrolytes used. There was an anodic peak at 0.16 V (versus Ag) and a cathodic peak at 0.12 V. Optical absorption spectra were measured at various levels of doping. The neutral film showed one peak at 3.5 eV, corresponding to the π‐π* transition. The oxidised film showed two peaks in the lower energy regions, suggesting it was in the bipolaron state. Scanning electron microscope (SEM) observation revealed a process of unique morphology formation.
