摘要：

Some differences in the UV-Vis-NIR light absorption spectra of camphorsulfonic acid-protonated polyaniline (CSA-PAn) solutions or thin films were observed. They are related to the molecular weight (MW), aggregation state of the polyaniline and to the counteranion nature. High MW polyaniline synthesized at low temperatures gives CSA-PAn films showing an enhanced polaron delocalization. The substitution of the CSA. counteranions by Cl- without intermediate deprotonation keeps the polaron delocalization state.
