The electronic structure of sodium-doped poly(pphenylenevinylene), or PPV, has been studied using photoelectron spectroscopy, UPS and XPS. Upon doping, two new states are created in the previously forbidden electronic bandgap. No finite densityof-states is observed at the Fetmi energy. The UPS spect
