Abstract

An alkynyl-protected gold nanocluster [Au24(CΞCPh)14(PPh3)4](SbF6)2 has been prepared by a direct reduction method. Single-crystal X-ray diffraction reveals that the molecular structure contains a Au22core that is made of two Au13-centered cuboctahedra that share a square face. Two staple-like PhCΞCAuCΞCPh motifs are located around the center of the rod-like Au22core. This Au24 nanocluster is highly emissive in the near-infrared region with λmax=925nm and the nature of the HOMO-LUMO transition is investigated by time-dependent DFT calculations. Good as gold: An alkynyl-protected gold nanocluster [Au24(CΞCPh)14(PPh3)4](SbF6)2 is reported which contains a Au22core composed of two Au13 centered cuboctahedra that share a square face. Two staple-like PhCCAuCCPh motifs are located around the center of the rod-like Au22core. The Au24 nanocluster is highly emissive in the near-infrared region (λmax=925nm). Atom colors: Au=orange; C=gray.
