Organic light emitting diodes (OLEDs) have shown great commercial application prospects in the fields of solid-state lighting and display, due to their novel optoelectronic and mechanical characteristics. In recent years, arylsilanes groups have received extensive attention in the synthesis of high-performance host materials for the electroluminescent device. Due to the easy modification and multi-function of the arylsilanes group, a host material with excellent performance can be synthesized by connecting functional units with different structures, in order to realize an efficient organic electroluminescent device. In this review, we start from the design and classification of materials and describe the current research status of arylsilanes host materials. The molecular structure design and synthesis, thermodynamic properties, photophysics properties, electrochemical properties, and electroluminescent device performance are summarized. Finally, the current problems of arylsilanes host materials in organic electroluminescent materials are discussed, and the perspective and development are also presented.
