ABSTRACT The preparation of dialkyl-substituted poly(2,5-didecyl-1,4-phenylene vinylene) ( PDDPV) by the Horner-Emmons polycondensation is described. Its performance in an organic light-emitting diode (OLED) device architecture is compared with devices prepared from the analogous dialkoxy-substituted poly(2,5-didecyloxy-1,4-phenylene vinylene) ( PDOPV) and the corresponding alkyl-alkoxy-substituted alternating copolymer. Additionally, the structure, stability, electrochemical, and optical properties of the PPVs were characterized by gel permeation chromatography, thermogravimetric analysis, NMR spectroscopy, cyclic voltammetry, UV-Visible spectroscopy, and fluorescence spectroscopy. © 2014 Wiley Periodicals, Inc.
