    Abstract:

    The characteristics of high nitrogen content, compact structure, low sensitivity, and good thermal stability make the bipyrazole structures ideal energetic backbones for the synthesis of high energy density materials. Based on different linkers, such as C─C, C─N and N─N, between monopyrazole moieties, recent progress of the five dipyrazole based energetic compounds, including 2H,2′H-3,3′-bipyrazole(Ⅰ), 1H,1′H-4,4′-bipyrazole(Ⅱ), 1′H-1,4′- bipyrazole(Ⅲ), 2"H-1,3"-bipyrazole(Ⅳ) and 1"H,2H-3,4"- bipyrazole(Ⅴ), is reviewed from the aspect of synthetic strategy, explosophore introduction and property evaluation. The development and research trends on the synthesis of bipyrazole energetic compounds are analyzed. The key development directions of bipyrazole energetic compounds in the future are as follows: screen reported bipyrazole energetic compounds with excellent performance for synthetic and application research; design and synthesize more bipyrazole compounds with excellent and comprehensive properties by explosophore and nitrogen-rich cation introduction; strengthen the studies on synthesis and properties of several bipyrazole units (such as 2"H-1,3"-bipyrazole(Ⅳ) and 1"H,2H-3,4"-bipyrazole(Ⅴ) and 1,1"-bipyrazole(Ⅵ)) and improve the research of bipyrazole energetic compounds.
