The invention relates to an organic compound containing phenanthrcarbazole and pyridine and an application of the organic compound, in particular to the application of organic electroluminescent diodes. The organic compound has the structural formula shown in structural formula (1), which is as shown in the specification. The organic compound can be used as a host material or a co-host material ofa phosphorescent OLED, especially a red OLED, through matching with a suitable object, especially a phosphorescent object or a TADF luminophor, the luminous efficiency and the service life of the organic compound as an electroluminescent device can be improved, and a solution for manufacturing a light emitting device with low cost, high efficiency, long service life and low roll-off is provided.In addition, a co-host is formed by matching with another host with hole transport property or bipolar property, and thus the electroluminescent efficiency and the service life of the device are improved. 本发明涉及种含菲咔唑和吡啶类的有机化合物及
