description A host material is provided to increase the current efficiency of a dopant releasing agent, to prolong the lifetime of the dopant releasing agent, to facilitate synthesis and refinement. A host material is indicated as the chemical formula 1 or 2. In the chemical formulae, Ar1 and Ar2 independently show phenyl, 1- naphthyl or 2- naphthyl. The organic electro luminescence device includes layers arranged with a transparent substrate, anode layer, hole-transport layer, light-emitting layer, electron-transport layer and cathode layer in order. The anode layer and cathode layer form the electric circuit in contact with the respective external power supply. The light-emitting layer comprises a host material indicated as the chemical formulae.
