Abstract

Energetic materials that are photoactive or believed to be photoactive may include a conventional explosive (e.g. PETN, nitroglycerine) derivatized with an energetic UV-absorbing and/or VIS-absorbing chromophore such as 1,2,4,5-tetrazine or 1,3,5-triazine. Absorption of laser light having a suitably chosen wavelength may result in photodissociation, decomposition, and explosive release of energy. These materials may be used as ligands to form complexes. Coordination compounds include such complexes with counterions. Some having the formula M(L) n 2+ were synthesized, wherein M is a transition metal and L is a ligand and n is 2 or 3. These may be photoactive upon exposure to a laser light beam having an appropriate wavelength of UV light, near-IR and/or visible light. Photoactive materials also include coordination compounds bearing non-energetic ligands; in this case, the counterion may be an oxidant such as perchlorate.

First claim

What is claimed is:

1. A compound of the formula

or of the formula

or of the formula

or of the formula

wherein X is selected from chloride, bromide, or iodide, and
wherein Y is selected from —OCH 2 C(CH 2 ONO 2 ) 3 , —OCH 2 C((F)(NO 2 ) 2 ), —OCH(ONO 2 ) 2 ,

or
wherein X is

and
wherein Y is

or
wherein X and Y are each independently selected from —OCH 2 C(CH 2 ONO 2 ) 3 , —OCH 2 C((F)(NO 2 ) 2 ), —OCH(ONO 2 ) 2 ,

or NH 2 ,
with the exception that if X is NH 2 , then Y is not NH 2 .

2. The compound of claim 1 , wherein the formula is

wherein X is selected form chloride, bromide, and iodide, and
wherein Y is —OCH 2 C(CH 2 ONO 2 ) 3 .

3. The compound of claim 1 , wherein X=Y=—OCH 2 C(CH 2 ONO 2 ) 3 .

4. The compound of claim 1 , wherein X=Y=—OCH 2 C((F)(NO 2 ) 2 ).

5. The compound of claim 1 , wherein X=Y=—OCH(ONO 2 ) 2 .

6. The compound of claim 1 , wherein X=Y=

7. The compound of claim 1 , wherein X=Y=
