copolymers containing electron-withdrawing 4-
tert-butylphenyl-1,3,4-oxadiazole-phenyl moieties as
side chains [66]. The photocurrents of the devices
fabricated from these polymers are enhanced in the
presence of the 1,3,4-oxadiazole moieties, thereby
leading to an improved power conversion efficiency.

By dispersing carbon black into POD-DPE, con-
ductive composites can be obtained. The presence
of carbon black enhances the thermal stability. The
resistivity decreases continuously with an increase
of pressure. Further, the composite shows a typical
semiconductor behavior, characterized by an increase
of conductivity ...
