Gold(I), Phosphanes, and Alkynyls: The Perfect Allies in the Search for Luminescent Compounds
A family of mixed phosphane/alkynyl gold(I) complexes was prepared by addition of PPh3 or PPh2py to suspensions of the polymeric species [Au(C=CR)n] [R = Ph, 2-pyridyl (py)] and [Au2{C=C(CH2)3C=C}]n. The resulting complexes are luminescent both at room and low temperature, in solution and in the sol...

| Summary: | A family of mixed phosphane/alkynyl gold(I) complexes was prepared by addition of PPh3 or PPh2py to suspensions of the polymeric species [Au(C=CR)n] [R = Ph, 2-pyridyl (py)] and [Au2{C=C(CH2)3C=C}]n. The resulting complexes are luminescent both at room and low temperature, in solution and in the solid state. The emissions are assigned to intraligand transitions associated with the C=C moieties or related to 3[s(Au–P)¿p*(C=Cpy)] transitions. The crystal structure of dinuclear complex [Au2{C=C(CH2)3C=C}(PPh2py)2] shows the presence of dimers stabilized by intermolecular aurophilic interactions. |
