Luminescent Gold( III ) Alkynyl Complexes: Synthesis, Structural Characterization, and Luminescence Properties

Luminous: The AuIII alkynyl complexes [Au(C^N^C)(CCR)] [HC^N^CH=2,6-diphenylpyridine, R=C6H5 (1), C6H4-Cl-p (2), C6H4-OCH3-p (3), C6H4-NH2-p (4); HC^N^CH=2,6-bis(4-tert-butylphenyl)pyridine, R=C6H5 (5)] were prepared, and the molecular structure of 1 was characterized (see picture). Complexes 1–5 display luminescence in solution and in the solid state both at low and ambient temperature.
