Due to conjugated planar molecular structure and additional N-oxide bonds， nitrogen-rich fused-ring N-oxides usually exhibit the advantages of high density， good detonation performances and good sensitivity and they have gradually become a research hotspot of energy materials. This article reviewed molecular structure， synthesis method and physical and chemical properties of twenty nitrogen-rich fused-ring N-oxides that were synthesized in the last decade. At the same time， this article compared some main physical and chemical properties between nitrogen-rich fused-ring N-oxides and their precursors. This review will provide some references for the synthesis and property investigation of new nitrogen-rich fused-ring N-oxides.
