摘要

The latest member of the azole family,the pentazolate or cyclo-N5-,has received increased attention since its first mass-spectral detection by Christe et al.in 2002.As it is carbon-and hydrogen-free,the pen-tazolate anion can release large amounts of energy while simultaneously decomposing to environmen-tally friendly nitrogen gas.Due to these attractive qualities,cyclo-N5-and related compounds are essential in the advancement of high-energy-density materials(HEDMs)research.This review aims to provide a consolidated report on all research done on cyclo-N5-,with a focus on pentazoles as energetic materials and on their experimental synthesis.Included in this review are the following:① the historical significance of cyclo-N5-;② precursors of cyclo-N5-;③ synthesis routes of cyclo-N5-with a focus on arylpentazole precursors;④ factors affecting the stability of cyclo-N5-;⑤ energetic performances of cur-rent energetic cyclo-N5--containing compounds;and ⑥ future possible experimental research.This review is a comprehensive summary of the current understanding of cyclo-N5-,in an effort to further understand the potential of this anion for adoption as a powerful and environmentally friendly next-generation explosive.
