Abstract

We investigated electroluminescence (EL) properties of electropolymerized poly-p-phenylene (PPP) films formed by means of electro-oxidative and electro-reductive methods. Electro-oxidatively polymerized PPP (O-PPP) and electro-reductively polymerized PPP (R-PPP) clearly demonstrated different light emitting behavior. In the case of electro-oxidative PPP, the intensity of light emission decreased with increasing quantity of polymerization charge, whereas with electro-reductive PPP, it increased with increasing quantity of polymerization charge. These different types of behavior of the two kinds of PPP films suggested the difference in depth profile of the regularity of molecular structures formed by the two different methods.
