Molecules featuring fluorine-containing functional groups exhibit outstanding properties with high density, low sensitivity, excellent thermal stability, and good energetic performance due to the strong electron-withdrawing ability and high density of fluorine. Hence, they play a pivotal role in the field of energetic materials. In light of current theoretical and experimental reports, this review systematically focuses on three types of energetic materials possessing fluorine-containing functional groups F- and NF - substituted trinitromethyl groups (C(NO ) F, C(NO ) NF ), trifluoromethyl group (CF ), and difluoroamino and pentafluorosulfone groups (NF , SF ) and investigates the synthetic methods, physicochemical parameters, and energetic properties of each. The incorporation of fluorine-containing functional moieties is critical for the development of novel high energy density materials, and is rapidly being adopted in the design of energetic materials.
由于氟具有强吸电子能力和高密度，含有含氟官能团的分子表现出出色的性能，如高密度、低灵敏度、优异的热稳定性和良好的能量性能。因此，它们在含能材料领域发挥着关键作用。根据当前的理论和实验报告，本综述系统地聚焦于三种含有含氟官能团的含能材料：F-和NF-取代的三硝基甲基基团（C(NO₂)₃F、C(NO₂)₃NF）、三氟甲基基团（CF₃）以及二氟氨基和五氟砜基团（NF₂、SF₅），并研究了每种材料的合成方法、物理化学参数和能量性能。含氟官能部分的引入对于新型高能量密度材料的开发至关重要，并且正在迅速应用于含能材料的设计中。
