Synthesis of New Alkynyl-Bridged 2,5-Disubstituted 1,3,4-Oxadiazoles

A synthesis of new alkynyl-derived 2,5-disubstituted 1,3,4-oxadiazoles through palladium/copper-catalyzed Sonogashira cross-coupling between oxadiazole-substituted phenyl bromides and various arylacetylenes is described. Investigation of the absorption and emission spectra of the target compounds indicates emission profiles in the near-blue and blue region and high luminescence intensities. The presented approach is very convenient for the synthesis of luminescent small-molecules or precursors of other complex derivatives that are useful in the preparation of OLEDs as electron-transporting components.

Preparation of functionalized polystyrene-block-polyisoprene copolymers and their luminescence properties

A series of block copolymers functionalized with aromatic 1,3,4-oxadiazole and stilbene derivatives have been synthesized by the palladium catalyzed reaction between polystyrene-block-polyisoprene and different functional units. These polymers exhibited different emission properties in solution and in the solid state. In chloroform solution, they showed relatively narrow and featured emission bands while, in the solid state, the emission band was broadened and showed a significant red shift. These observations were attributed to the formation of aggregates between the luminophores. After some oxadiazole functionalized copolymers were annealed at elevated temperature, such aggregation was enhanced and there were further changes in the emission spectra. For the bifunctional copolymers, such a shift in the emission band was not significant because the presence of two different chemical species in the same block may prevent the same type of luminophores from aggregating together.
