The electrical properties of 4,4′-bis(4-styryl-styryl) benzene oligomer based diodes were investigated by d.c and a.c measurements. At high field, the charge carriers are injected through potential barriers at the interface and the transport occurs via a field assisted thermal ionization process in the bulk of the oligomer. The influence of the metal electrode revealed in the current-voltage characteristics...
Investigations of phenylene vinylene oligomer thin films with 7 phenyl, 6 vinyl units (6PV) have been performed by optical and electrical measurements. The optical characterizations including infrared, Raman and UV-VIS spectroscopies were discussed by comparing the results with those obtained in poly(p-phenylene vinylene) (PPV). The electrical properties of oligomer based diodes were studied by measuring...
