A light emitting composition includes a light-emitting lumophore-functionalized nanoparticle, such as an organic-inorganic light-emitting lumophore-functionalized nanoparticle. A light emitting device includes an anode, a cathode, and a layer containing such a light-emitting composition. In an embodiment, the light emitting device can emit white light.

N-chlorosuccinimide and 1,8-diazabicyclo[5.4.0]undec-7-ene oxidatively cyclizes structurally diverse acyl hydrazone, thereby providing an efficient and convenient method for the synthesis of various 2,5-disubstituted1,3,4-oxadiazoles. The salient features of this method are mild reaction conditions, short reaction time, excellent yields, and simple workup procedure.
