A solvent-free dense energetic metal–organic framework (EMOF): to improve stability and energetic performance via in situ microcalorimetry

Abstract

It is a tremendous challenge to prepare solvent-free dense energetic metal-organic frameworks (EMOFs), hence also to improve their stability and energetic performance. In this study, based on in situ microcalorimetry, an interpenetrating EMOF without solvent molecules, [Cu(tztr)]_n (1, H₂tztr = 3-(tetrazol-5-yl)triazole) was obtained, possessing high stability (T_dec = 360 °C) and outstanding energetic properties (ΔH_det = 7.53 kcal cm^-3, D = 8.429 km s^-1, P = 40.02 GPa).
