Photochemistry : A series of emissive gold(III) complexes with fluorene‐containing cyclometalating ligands exhibits strong phosphorescence and long‐lived excited states with emission quantum yields and lifetimes up to 58 % and 305 μs, respectively. These complexes can sensitize energy up‐conversion of 9,10‐diphenylanthracene (DPA; see picture) and display rich two‐photon absorption properties (TPA; TTA=triplet–triplet annihilation).
