A

Over

Here,
an
innovative
organic
explosive,
(E)-1,2-bis(3-azido-5-(trifluoromethyl)-4H-1,2,4-triazol-4-yl)diazene
(4),
designed

through

reagents.
Importantly,
this
integrated
two
trifluoromethyl
azido
groups
into
N,N′-azo-1,2,4-triazole
backbone
to
enhance

With
combination,
it

being

possessing

It
shows
