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)n2+ 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.
具有光活性或被认为具有光活性的活性材料可能包括与能量吸收紫外线和/或可见光色团(如1,2,4,5-四唑或1,3,5-三唑)衍生的传统爆炸物(例如PETN,硝化甘油)。吸收具有适当选择波长的激光光线可能导致光解、分解和爆炸释放能量。这些材料可以用作配体形成配合物。配位化合物包括具有对离子的这些配合物。一些具有M(L)n2+公式的化合物已经合成,其中M是过渡金属,L是配体,n为2或3。这些化合物在暴露于具有适当波长的紫外线、近红外和/或可见光的激光光束时可能具有光活性。光活性材料还包括携带非活性配体的配位化合物;在这种情况下,对离子可能是诸如高氯酸盐之类的氧化剂。
