Abstract Thermal stability of energetic materials determines their applicability under high temperature conditions, while few could achieve thermal decomposition peak temperatures above 450°C. Based on a novel nitrogen‐rich fused heterocyclic skeleton, bis[1,2,4]triazolo[1,5‐b;5’,1’‐f][1,2,4,5]tetrazine‐2,7‐diamine (DATC) demonstrated super compared to traditional heat‐resistant structures. Herein, detailed exploration was conducted the behaviors and properties DATC through conventional methods combined with tandem techniques, including in‐situ FTIR DSC/TG‐FTIR‐MS quadruple analysis. The experimental results were those 2,2’,4,4’,6,6’‐hexanitrostilbene (HNS) 3,5‐dinitro‐N,N’‐bis(2,4,6‐trinitrophenyl)pyridine‐2,6‐diamine (PYX), two famous widely applied. major exothermic found around 479°C heating rate 10°C ⋅min −1 corresponding onset 430°C. process most likely initiated from decompositions amino groups further destructed molecular which lead series fragments NH 2 (m/z=16), CN (m/z=26), HCN (m/z=27), N (m/z=28), H (m/z=30), (m/z=42), HN 3 (m/z=43), C (m/z=52). Obviously, do not contribute much DATC's performances, condensation triazole moieties result in great skeleton. Both mechanism different HNS PYX.
