We have measured the photocurrent action spectra of the conjugated polymers poly[2-methoxy, 5 ethyl (2\ensuremath{'} hexyloxy) paraphenylenevinylene] (MEH-PPV) and poly(phenylenevinylene) (PPV) in sandwich cells between indium tin oxide (ITO) and alu

We have fabricated single-layer organic electroluminescent diodes with poly( para -phenylene vinylene) (PPV) and poly(2-methoxy-5-ethyl(2′-hexyloxy) para -phenylene vinylene) (MEH-PPV), using indium-tin oxide (ITO) or semi-transparent gold as hole-

In this work we report the synthesis and characterization of processable poly(aromatic oxadiazole)s. The polymers are rendered processable by either dissolving the polymer in strongly acidic organic solvent or by the thermal conversion of a soluble p

New oxadiazole-based polymeric materials have been synthesized either as side chain copolymers with polymethacrylate or as main chain copolymers carrying solubilizing elements such as hexafluoropropylidene or meta-linked aromatic spacer units. Many o

Flash photoexcitation of dilute solutions of fully conjugated poly(2,5-dialkoxyphenylenevinylene)s results in a transient change in the microwave conductivity. Gel formation resulting from aggregation of polymer chains in some of the solutions leads

A one-pot polycondensation of 4,4′-(hexafluoroisopropylidene)bis(benzoic acid)1 with terephthalic dihydrazide 2 and/or hydrazine sulfate 3 affords aromatic oxadiazole polymers 4, 5 and 6, respectively, the optical and electrochemical properties of
