The most explosive substances known to man

Heres the most explosive ones I know of:

Octanitrocubane

thats supposedly the most explosive compound known. Cubane itself is extremely rare and difficult to make so octanitrocubane is not feasible at all to produce. Its the nitro groups in TNT that give the compound its explosive properties so octanitrocubane, having 8 nitro groups is kinda like TNT on steroids. I retract that. Its like TNT on phencyclidine (PCP).

HMX

This compound is a more explosive analogue of RDX.

Hexanitrohexaazaisowurtzitane

This compound is another nitramine like RDX and HMX but as you can see it has a dog kennel shaped carbon skeleton which allows 6 nitramino groups to be attached. Since it has more nitramino groups, its even more powerful than HMX.

Nitroglycerin

From what I read, nitroglycerin is actually more powerful than all those compounds above but its practicality is limited by its instability. I don't understand how nitroglycerin could be more powerful than octanitrocubane though. It only has 3 nitro groups and since its a liquid at room temperature, it must be far less dense. Why is it so explosive?

Thats all I know about, I learned all this reading an article on explosives the other day. List any other powerful substances you know of.

Are you asking about "the most sensitive" explosives as your post title would imply? Or "the most powerful" as your post would imply.

There's an inherent problem in asking about the most powerful explosive, as there are a number of measures used including brisance, detonation velocity, power/performance, product volume, etc.
Explosives are actually used in various ways depending on these values.

Ah right. I don't know shit about explosives.

Well this is a place to learn. I think learning about those terms will give you a more comprehensive understanding. You have to start somewhere.

You know what i find particulairly beautiful? The intricate moleculair structures of HE's. Just look at the structure of HMX for example, it's elegant and a poweful compound to be sure.

Sorry for the offtopic post. Just felt like sharing that.

I had an idea for something possible even more powerful...

Liquified SF6 under pressure mixed with pentaborane.
SF6 is, surprisingly completely non-toxic and non-reactive, while pentaborane is a potent neurotoxin and is pyrophoric. It would be rather dangerous to handle.
