Tunable copper complexes with functional ligands: A promising strategy for green primary explosives

Exploring alternatives of lead-containing primary explosives (lead azide, LA; lead styphnate, LS) has always been a pressing issue in the field of energetic materials. Although some lead-free primary explosives based on tetrazole have been reported, there are no qualified products that really replace LA. In this research, four energetic coordination polymers [Cu3(ATZ)2(N3)6]n (CAA-1), [Cu(ATZ)2(N3)2]n (CAA-2) (ATZ = 4-amino-1,2,4-triazole),...
