| 英文摘要 | In this study, 1,2-bis(diphenylphosphino)ethane (dppe) ligands are used to synthesize gold nanoclusters with an icosahedral au-13 core. the nanoclusters are characterized and formulated as [au-13(dppe)5cl(2)]cl-3 using synchrotron radiation x-ray diffraction, uv/vis absorption spectroscopy, electrospray ionization mass spectrometry, and density functional theory (dft) calculations. the bidentate feature of dppe ligands and the positions of coordinating surface gold atoms induce a helical arrangement that forms a propeller-like structure, which reduces the symmetry of the gold nanocluster to c-1. therefore, dppe ligands perform as a directing agent to create chiral an ansa metallamacrocycle [au-13(dppe)(5)cl-2](3+) nanocluster, as confirmed by simulated electronic circular dichroism spectrum. the highest occupied molecular orbital (homo)-lowest unoccupied molecular orbital (lumo) gap of the [au-13(dppe)(5)cl-2](3+) cluster is determined as approx. 1.9 ev, and further confirmed by ultraviolet photoemission spectroscopy analysis and dft simulation. furthermore, the photoactivity of [au-13(dppe)(5)cl-2](3+) is investigated, with the nanocluster shown to possess near-infrared photoluminescence properties, which can be employed for o-1(2) photogeneration. the quantum yield of o-1(2) photogeneration using the [au-13(dppe)(5)cl-2](3+) nanocluster is up to 0.71, which is considerably higher than those of anthracene (an organic dye), and au-25 and au-38 nanoclusters. |
