Femtosecond transient absorption studies of two novel energetic tetrazole derivatives

چکیده
Excited-state dynamics of two novel energetic nitrogen-rich aryl-tetrazole molecules were investigated using femtosecond transient absorption spectroscopy. The internal conversion from Sn to S1 occurred in the 0.3–0.5 ps; vibrational relaxation within states transpired a 1.8–5 ps time scale and, subsequently, intersystem crossing was observed with lifetimes 7.8 and 129 ps. nitro-substituted tetrazole demonstrated faster decay weaker fluorescence compared amino-substituted derivative. We believe that high nitrogen content former resulted possible more rapid nonradiative decay.

The synthesis of 3-amino-1-nitroguanidine (3-ANQ) and 5-hydrazino tetrazole (5-HT) derivatives as new energetic materials are described. Reaction of 3-ANQ with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-HT. Addition of NaN3 to a mixture of 3-ANQ and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excelle...
