摘要：

In-situ studies which combine photoelectron and electron energy loss spectroscopies permit the determination of both, the occupied and unoccupied gap states within the electronic structure of polypyrrole films over a wide range of doping levels. Doping induces polaronic states which with increasing concentration broaden and cause a metallic density of states. At intermediate doping levels, first direct experimental evidence is given for repulsive electron-electron interactions among polarons. There is no indication of bipolarons within this 1-dimensional polymer. © 1990.
