ANFF-34 and ANFF-43 were unambiguously identified using comparative studies of 15N NMR and single-crystal X-ray diffraction. Moreover, their thermal behaviours, and non-isothermal thermodynamic parameters were systematically investigated. Both ANFF-34 (Tm: 116.2 °C, Td: 255.4 °C) and ANFF-43 (Tm: 106.2 °C, Td: 255.6 °C) have similar thermal decomposition processes to that of DNTF. The superior performances
尽管高能区域异构体由于其有趣的结构-性质相关性而引起了广泛关注,但它们的有效合成和准确识别仍然非常困难。在本文中,我们合成了两种高能区域异构体,即 3-(4-aminofurazan-3-yl)-4-(4-nitrofurazan-3-yl)furoxan (ANFF-34) 和 4-(4-aminofurazan-3- yl)-3-(4-nitrofurazan-3-yl)furoxan (ANFF-43),通过可控策略分别提高了 32% 和 38% 的收率。ANFF-34 和 ANFF-43 的结构通过15 N NMR 和单晶 X 射线衍射的比较研究明确确定。此外,系统地研究了它们的热行为和非等温热力学参数。ANFF-34(T米: 116.2 °C, T d : 255.4 °C) 和 ANFF-43 ( T m : 106.2 °C, T d : 255.6 °C) 具有与 DNTF
