摘要：
A series of (L)MX (L=isocyanide; M=Cu(I) or Au(I); X=chloride or carboranyl) complexes have been prepared. The first examples of isocyanide Cu(I) chloride complexes with 1 : 1 stoichiometry between isocyanide and CuCl are reported and structurally characterised. The photophysical properties of (RNC)AuCl and (RNC)Au(eta 1-carboranyl) complexes have been investigated. Complexes (RNC)Au(eta 1-carboranyl) show no aurophilic Au-Au interactions and emit long-lived deep-blue phosphorescence up to 377 mu s. The radioluminescence of these gold complexes was studied to show a superior radioluminescence stability for the gold(carboranyl) complexes compared to gold chloride materials under constant high energy X-ray radiation of 350 keV.
