Front Cover: Versatile Emissive Three‐Coordinated Gold(I) Systems‐Properties and Perspectives (Eur. J. Inorg. Chem. 38/2021)

Abstract

The Front Cover shows different ligands with phosphorus, nitrogen, carbon, or other donor atoms, used as building blocks for the construction of three‐coordinated gold(I) complexes. These ligands may or may not be emissive, but their selection, together with different distortions from the ideal geometry around the gold atom, leads to luminescent three‐coordinated complexes with different emission energies. Triplet harvesting, reported for some of these complexes, is desirable for building devices used, for instance, in mobile phones. In addition, changes in molecular disposition in the solid phase upon exposure to different solvents or VOCs allow tuning the emissive properties. The authors thank the GEQO group of the Spanish Royal Chemical Society (RSEQ) for their kind invitation to contribute to the RSEQ‐GEQO Prize Winners Special Collection.
