Zusammenfassung
We prepared two chlorido-gold(I) complexes of the type L-Au-Cl bearing a naphthyl moiety: Complex 1 with L = tris-1-naphthyl-phosphine shows standard linear coordination without further aggregation in the solid state. Complex 2 with L = 2-naphthyl-isonitrile is engaged in a complex network of aurophilic and pi-pi interactions. The two complexes show similar luminescence behaviour in solution at ...

We prepared two chlorido-gold(I) complexes of the type L-Au-Cl bearing a naphthyl moiety: Complex 1 with L = tris-1-naphthyl-phosphine shows standard linear coordination without further aggregation in the solid state. Complex 2 with L = 2-naphthyl-isonitrile is engaged in a complex network of aurophilic and pi-pi interactions. The two complexes show similar luminescence behaviour in solution at room temperature with both intraligand fluorescence and phosphorescence. At 77 K the emission spectra are dominated by intraligand phosphorescence, which is typical of gold complexes with extended pi-chromophores. (C) 2016 Elsevier B.V. All rights reserved.
