ResumenRecent interest in luminescent metal complexes has been driven by possible applications in OLED display technology as dopant emitters, in solar photoconversion chemistry as chromophores, and in sensor development for luminescence detection. Potentially attractive in this regard are gold(I) complexes that, in many cases, possess intense, long-lived luminescence in the solid state or in solution with emission energies spanning the visible spectrum. Part of the fascination of gold(I) chemistry is due to the frequent formation of inter- and intra-molecular gold-gold interactions (aurophilicity) and the tendency to adopt linear coordination. Two common strategies in the synthesis of gold(I) compounds consist in the use of a) reactions between gold complexes with the gold center as acid and some basic ligands, or b) reactions in which the gold center can be the base and can interact with acid complexes. The required conditions for a gold complex to show luminescence depend of the nature of the ligands, the geometry around the gold center or the presence of gold-gold interactions in the complexes. Nevertheless, the conjunction of more than one of these conditions makes the assignment more complicated. In addition, the presence of new metal centers can modify the relative energy of the frontier orbitals of gold and create new orbitals, as a consequence of the gold–metal interaction. We will see some examples of three-coordinate complexes, with gold-gold or gold-thallium interactions, with charge-transfer or intraligand transitions.
