We describe some novel poly(p-phenylene vinylene) (PPV) derivatives of improved lifetime and luminescence. Electronic transport in these light emitting polymer materials has been studied using transient time-of-flight techniques. The effect of defects arising from the polymerisation process was investigated on carrier mobility and trapping. The same defects play crucial role in the lifetime of organic electroluminescent devices.
