Fluorine-Containing Functional Group-Based Energetic Materials.

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 2 - substituted trinitromethyl groups (C(NO 2 ) 2 F, C(NO 2 ) 2 NF 2 ), trifluoromethyl group (CF 3 ), and difluoroamino and pentafluorosulfone groups (NF 2 , SF 5 ) 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.
