i readed in the article about borazine in wiki that "Among other B-N type compounds mixed amino-nitro substituted borazines have been predicted to
outperform carbon based explosives such as CL-20"
they talking about partialy nitrated borazine? if so it has been syntisized and studied by now??.
wher i can get more information about it?

Check this one:

Paradoxically having a high heat of explosion does not correspondingly result in high explosion pressure or
brisance. Velocity is also markedly less for compounds in which boron substitutes carbon. Interesting concept , why I looked into it , but the
literature is not encouraging. The fact that refractory ceramic B2O3 is a detonation product is much to blame since the energy is radiated as heat (
infrared ) rather than retained by the molecules as kinetic gas pressure. Substituting Fluorine should theoretically improve matters since BF3 is
itself gas although the heavy molecular weight means fewer gas molecules as detonation products.
Here is something I thought up , balanced for reduction - oxidation. Products are 3 BF3 + 3 HF + 6 N2
* Note that these products are hazardous and would preclude military application under treaties banning chemical agent use.

so nitro-borazines has been synthesized and studied?? the first links(from Dany) talk about it as theoretical compound.
and more questions about that amino fluoro borazines:
they has some significant advantage over nitro organic compounds?.
they are similar to nitro borazines in their actual preformance?.
how those fluoro borazines can be synthesized??.
