| Two new copolymers, poly(2,5-didecyl-1,4-phenylenevinylene-alt-9,9-didecylfluorenyl-2,7-vinylene) and poly(2,5-didecyloxy-1,4-phenylenevinylene-alt-9,9-didecylfluorenyl-2,7-vinylene), were prepared via Horner-Emmons coupling. The polymers were characterized by gel permeation chromatography (GPC), NMR spectroscopy, UV-vis spectroscopy, fluorescence spectroscopy, thermogravimetric analysis (TGA), and cyclic voltammetry (CV). Comparison of the UV-vis and fluorescence spectra of the copolymers to those of the homopolymer poly(9,9-didecylfluorenyl-2,7-vinylene) revealed small bathochromic shifts for the copolymers. A comparison of the stability of the polymers under thermal and electrochemical stress as well as an examination of their working lifetime in a light-emitting diode configuration will be presented. |
