摘要
The present invention relates to a specific combination of a host compound and a multiple-deuterated guest compound, and an optoelectronic device comprising the composition. The composition of the present invention has a good thermal stability, and can balance the transport of holes and electrons. The energy transmission between the host and the guest is more efficient, which is particularly manifested in the fact that the composition of the present invention is used as the light-emitting layer of an organic electroluminescent device, the current efficiency of the light-emitting device is improved, and the driving voltage is reduced.
