摘　　要：The long sought cubic gauche polymeric nitrogen(cg-N)consisting of N-N single bonds has been synthesized by one pot route using sodium azide as a precursor at ambient conditions.The recrystallization process was designed to expose crystal faces with low activation energy that facilitates initiating the polymeric reaction at ambient conditions.The azide was considered as a precursor due to the low energy barrier in transforming double bonded N=N to single bonded cg-N.Raman spectrum measurements detected the emerging vibron peaks at 635 cm^(−1) for the polymerized sodium azide samples,demonstrating the formation of cg-N with N-N single bonds.Different from traditional high-pressure technique and recently developed plasma enhanced chemical vapor deposition method,the route achieves the quantitative synthesis of cg-N at ambient conditions.The one pot synthesis of cg-N offers potential for further scaling up production as well as practical applications of polymeric nitrogen based materials as high energy density materials.
