Kurzbeschreibung (Abstract)
A novel electroluminescent poly(p-phenylenevinylene) (PPV) derivative was synthesized via the Gilch route, which emits in the blue-greenish region. The required monomer synthesis is a multistep process starting from catechol and does not involve any critical step. The polymer synthesis itself proceeds via standard Gilch conditions and results in constitutionally homogeneous and extraordinary high-molecular-weight PPVs. The characterization of these materials was carried out using nuclear magnetic resonance spectroscopy and size exclusion chromatography measurements. The highest occupied molecular orbital and lowest unoccupied molecular orbital energy levels were estimated by combining information provided by cyclic voltammetry and UV-vis measurements. Finally, the electroluminescent behavior of the polymer was confirmed in an organic light-emitting diode.
