Organic light emitting diodes (OLEDs) have gained tremendous attention due to their significant potential applications in flat-panel displays and solid state lighting. Blue electrophosphorescent devices are bottlenecks of research of OLEDs because of efficiency and stability, the choice of host materials for blue electrophosphorescence is very important. This review summarizes the recent progress in organic small molecules host materials for blue phosphorescent organic light-emitting diodes, focusing on the design strategies and device performance. Different type host materials including hole-transport-type host materials, silane-based host materials, electron-transport-type host materials, bipolar transport host materials and solution-processed host materials for blue electrophosphorescence are summarized with their structures, features and corre-sponding devices performance. Finally, the direction of development of organic small molecule host materials for blue electrophosphorescence is prospected.
