Synthesis and luminiscence properties of alkynyl gold complexes featuring carbazole fragments

Resumen del póster presentado a la XXXVIII Reunión Bienal de la Real Sociedad Española de Química, celebrada en el Palacio de Congresos de Granada, del 27 de junio al 30 de junio de 2022.During the last decades, the interest in gold(I) alkynyl complexes has been increasing as a consequence of their applications in different fields such as catalysis, pharmaceuticals and photochemistry. The combination of linear coordinated gold(I) complexes and both linearity and π-unsaturated nature of the alkynyl ligand make these complexes interesting building blocks for the construction of oligomers and polymers. The capability of gold atoms to make supramolecular interactions with other d10 cations such as Cu(I) or Ag(I) and the versatility of the alkyne to be functionalized with different chromophores make these compounds adequate candidates for the development of OLED materials and electronic devices. For this work, we have focused on the compound 9-(4-ethynylphenyl) carbazole, due to the luminescent properties of the carbazole fragment. Changes in the luminescence properties of gold complexes featuring these fragments have been previously reported when conditions such as solvent or temperature are modified. We have synthesized and studied the luminescence properties of carbazole-containing alkynyl gold(I) complexes with different ancillary ligands such as phosphines, amines, isocyanides and N-heterocyclic carbenes.Peer reviewe
