Abstract

The invention relates to a fused ring organic compound and a mixture and organic electronic device comprising the same. The fused ring organic compound shown in a general formula (I) has excellent electron transport properties and stability, material synthesis is simple, and when a synthesized material is applied to a device host material, the luminous efficiency and stability of the device can beimproved, and the production cost of the device can be reduced. In addition, a co-host can be formed through cooperation of the fused ring organic compound with another host with a hole transport property or a bipolar property, the electroluminescent efficiency and the service life of the device can be improved further.
