We report the design, synthesis, and application of a (N^C^C)‐ligand framework able to stabilize highly electron‐deprived gold(III) species. This novel platform enabled the preparation of C(sp 2 )‐gold(III) fluorides for the first time in monomeric, easy‐to‐handle, bench‐stable form by a Cl/F ligand‐exchange reaction. Devoid of oxidative conditions or stoichiometric use of toxic Hg salts, this method was applied to the preparation of multiple [C(sp 2 )‐Au III ‐F] complexes, which were used as mechanistic probes for the study of the unique properties and intrinsic reactivity of AuF bonds. The improved photophysical properties of [(N^C^C)Au III ] complexes compared to classical pincer (C^N^C)‐Au systems paves the way for the design of new late‐transition‐metal‐based OLEDs.
