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高能材料可包括用高能紫外线吸收和/或紫 外可见光吸收发色团(如 1,2,4,5-四嗪或 1,3,5-三嗪)衍生的传统爆炸 物(如 PETN、硝化甘油)。吸收适当波长的激光可导致光解离、分解和爆炸性能量释放。这些材料可用作配体形成配合物。配位化合物包括这类带有反离子的络合物。其中 M 是过渡金属,L 是配体,n 是 2 或 3。当暴露在具有适当波长的紫外光、近红外光和/或可见光的激光束下时,这些化合物可能会产生光活性。光活性材料还包括含有非能配体的配位化合物;在这种情况下,反离子可以是氧化剂,如高氯酸盐。
