Phenanthro[9,10-d]-imidazole(PI) unit has attracted extensive attentions in organic optoelectro-nic field due to its intrinsic wide band gap, high luminescence efficiency, good thermal stability, balanced charge carrier injection and transport property as well as low fabrication cost. In this manuscript, the recently reported blue electroluminescent PI derivatives were reviewed. The structure characteristics of PI were demon-strated, and the structure-property relationships of some PI derivatives were summarized systemically. At last, all the reported highly efficient nondoped deep blue emitters were summed up in order to comprehensively evaluate the potentials of PI derivatives in organic light emitting diodes( OLEDs) in the future.
