Four novel dinuclear N-heterocyclic dicarbene Au(I) complexes with a propylene linker between the carbene moieties were synthesized and their luminescence and electrochem. properties, together with their reactivity towards Br oxidative addition, were screened. The mol. structures of two complexes were determined by x-ray crystallog. All the complexes emit in the solid state in the blue-green spectral range (400-500 nm) with appreciable intensities (Φem up to ≈10%). In cyclic voltammetry, the Au(I)/Au(0) peak splits at low temperature into two sep. peaks relative to the couples Au(I)-Au(I)/Au(i)-Au(0) and Au(I)-Au(0)/Au(0)-Au(0), thus indicating the presence of an Au···Au interaction in the dinuclear complex. Oxidative addition of Br affords as a major or unique product Au(II)-Au(II) complexes most likely as a consequence of the interaction between the two Au centers favored by the propylene linker.
Dalton Transactions published new progress about Au-Au bond. 1003-21-0 belongs to class imidazoles-derivatives, and the molecular formula is C4H5BrN2, Recommanded Product: 5-Bromo-1-methyl-1H-imidazole.
