The construction and modification of novel energetic frameworks to achieve an ideal balance between high energy density good stability are a continuous pursuit for researchers. In this work, fused [5,6,5]-tricyclic framework was utilized as the host encapsulate oxidant molecules first time. A series new pyridazine-based [5,6] [5,6,5] polycyclic nitrogen-rich skeletons their derivatives were designed synthesized. Two strategies, amino oxidation host-guest inclusion, used modify skeleton in only one step. All compounds exhibit comprehensive properties (
