A pyrene tetraalkynyl ligand has been used for the
preparation of three different tetraalkynyl Au(I) complexes. Two
of these complexes display fluorescent emission in CH2Cl2
solution, with quantum yields exceeding 90%. Although the
emission is mainly due to ligand-centered excited states, the
presence of the metal center is key to reaching such excellent
quantum yield values, providing an extra rigidity to the system
and therefore, minimizing the nonradiative deactivation pathways.
To the best of our knowledge, these quantum yields lie
among the highest reported for metal-based luminophores in
solution, a quality that makes them resemble molecular torches. Preliminary studies on healthy cheek cells show that one of the
complexes is efficiently and rapidly taken up into the cell. [-]
