The latest research progress of layered crystal packing energetic materials at home and abroad is overviewed,and the design strategies of layered energetic materials are discussed in details.The first category is driven by experience and intuition of chemists,with the typical methods including internal cyclization reaction,bilateral modification,intra-layer hydrogen bond matching,face-to-faceπ-πstacking strategies,etc.The second category is based on theoretical quantum chemistry simulations,and the design ideas usually come from searches for thermodynamically stable dimers as well as predictions of crystalline structures.The third category is the machine learning approach,which has shown great advantages over the field of efficient screening of layered stacking patterns and predictions of related properties.Finally,the perspectives of the future development for design of layered energetic materials are presented,the examples including the investigation of intrinsic principles hidden in structure-activity relationships of layered energetic materials using statistical tools and the construction of a family of featuring methods that manage to describe layered energetic materials with good accuracies.85 references are attached.
