Dopant uptake in sodium-doped poly(p-phenylene vinylene) (PPV) has been measured, and e.s.r. spectroscopy has been used to follow the changes in unpaired spin concentration as the doping reaction proceeds. 2H n.m.r, line shapes of sodium-doped, ring-deuterated PPV (PPV-d4) have also been studied to observe the effects of doping. They contain two distinct components, one of which is attributed to hydride formation. The overall pattern is insensitive to temperature changes.
