Pushing the Performance Boundaries of Highly Energetic Bis(1,2,4-triazoles) through Merging Dual Strategies of C-Azo Bridging and -Nitramino Functionalization.

In this work, by combining the energetic -N═N-, -NO, and N-NH/N-NHNO groups with triazole, -amino compound and -nitramino compound were synthesized. Compound has a unique crystal structure, exhibiting enhanced energetic properties ( = 8996 m s, and = 34.0 GPa) and stability ( = 202 °C, IS = 21 J, and FS = 216 N) comparable to that of hexogen (RDX). Compound exhibits a high density (1.91 g cm) and excellent detonation performance ( = 9627 m s, and = 41.0 GPa), and hydroxylammonium salt exhibits exceedingly excellent detonation performance ( = 9677 m s, and = 41.3 GPa).
