Synthesis and Characterization of MEH-co-Oxadiazole Poly(p- phenylenevinylene) Copolymer

Poly(p-phenylenevinylene)s (PPVs) have received a great deal of interest due to their unique physical properties such as conductivity, electroluminescence, and solubility of selected derivatives, which allows for facile processing in the manufacture of microelectronic devices. Polymer-based conjugated materials offer the advantage of being directly processible from solution, permitting deposition through spin and blade coating under atmospheric conditions. We attempted synthesis of stable polymers possessing oxadiazole, alkylfluorene and phenylenevinylene linkage in the main chain and investigated its properties. The resulting MEH-co-Oxadiazole PPV copolymer was characterized by infrared spectroscopy, scanning electron microscopy, atomic force microscopy, and transmission electron microscopy, photoluminescence spectra(PL) and compared with the homopolymer.
