Charge-carrier mobilities and charge conduction in a poly(p-phenylenevinylene) derivative carrying an electron-transporting moiety

A PPV derivative carrying an electron-transporting PBD moiety, with much enhanced external quantum eAciencies, has been synthesized and studied by means of time-of-flight (TOF) and J ‐V measurements. As a result, the mechanism of the enhanced external quantum eAciencies, i.e., the mobility balancing of positive and negative charge carriers, was revealed, as well as the spacecharge limited conduction with an exponential trap distribution. ” 2001 Elsevier Science B.V.
