In this work, a gold nanocluster [Au(2-SAdm)(Dppe)] was synthesized and structurally determined by X-ray crystallography. The crystals of this cluster exhibit a 50-fold enhancement in quantum yield (5.05% for crystals) compared with its solution. Crystallographic analysis reveals that the weak intermolecular interactions (C-H⋯π, π⋯π) can inhibit the molecular vibration and thus generate the crystallization-induced emission enhancement phenomenon.
在这项工作中，合成了金纳米团簇[Au(2-SAdm)(Dppe)]，并通过X射线晶体学确定了其结构。该团簇晶体的量子产率（晶体为5.05%）与其溶液相比提高了50倍。晶体学分析表明，弱分子间相互作用（C-H⋯π、π⋯π）可抑制分子振动，从而产生结晶诱导发光增强现象。
