The X ligand has shown to control the volatility of the complex by means of steric hindrance; as the size of X increases, the intramolecular interactions between the precursor molecules, specifically the aurophilic interactions, decrease

While this approach to alkyl radical formation has been exploited in the synthesis of small organic molecules [35][36][37][38][39

• spectra, ions of the form [Au(CHx)y]−, [AuCO2(CHx)y]− and [AuCO(CHx)y]− are observed (Figure 9b). The data indicate that some of the layer may be bound to the Au substrate via Au–C bonds ([Au(CHx)y]−). In light of the XPS data in which metal–carbon bonds were not observed, the number of Au–C bonds would

• crosslinking. Decyl radicals generated under photochemical conditions (see Scheme 1, Equation 2) can be converted to decane (Scheme 1, Equation 3) or undergo inefficient grafting to the metal surface to generate Au–C bonds. The species 11 (Scheme 3) represents a decyl chain in which R can be H (decane adsorbed

• , which can be explained by the breaking of degeneracy of one empty and two occupied states. Other molecular states are relatively unaffected compared to C60/Au(111). When the vacancy is adsorbed towards the substrate, the Au–C bonds result in the broadening of the molecular spectrum, and there are broad
