Zinc-based light-emitting materials containing oxadiazole moieties

Two oxadiazole-based zinc complexes containing naphthalene moiety with different coordination site are synthesized and characterized. Their thermal stability, photoluminescent and electroluminescent properties are investigated. The resulting complexes have good thermal stability and show bright blue fluorescence in the solid state. Their electroluminscent wavelengths are dependent on the coordination site of naphthalene moieties.
