We report the synthesis and characterization of poly(9,9-dioctyl-1,4-fluorenylenevinylene), PDO14FV. This polymer is a novel poly(arylenevinylene) with fluorene units and long chain substituents that ensure solubility in organic solvents. PDO14FV presents green photoluminescence and yellow–green electroluminescence. The estimated ionization potential of PDO14FV is 5.3 eV and its estimated electroaffinity 2.5 eV. Organic light-emitting diodes based on PDO14FV were constructed, showing electroluminescent intensity onset at ca. 6 V.
