| 中文摘要: |
| 本研究选择柔性的硫属环己硫醇配体和三氟甲烷磺酸银盐在无模板的情况下自组装得到了一例“鱼”状Ag簇基一维链，其结构基元为Ag20(CyhS)20 (缩写为：Ag20S20, CyhSH = 环己硫醇)。这个“鱼”状的单元沿着a方向上重复生长为无限延长的一维银多团簇。Ag离子之间的亲银作用以及外端配体通过Ag–S作用共同稳定Ag簇内核。化合物Ag20S20的结构和组成通过单晶X射线衍射(XRD)、电喷雾飞行时间质谱、热重分析和傅里叶变换红外(FT-IR)确定。固体紫外可见吸收光谱表明Ag20S20是一种宽带隙半导体。光电流测试结果表明Ag20S20具有良好的光电流响应。 |
| 英文摘要: |
| In this study, a ‘fish-like’ Ag20S20 structural motif with the molecular formula Ag20(CyhS)20 (Abbreviated as Ag20S20, CyhSH = cyclohexanethiol) was obtained by self-assembling and combining a selectively flexible thiocyclohexane thiol ligand and silver trifluoromethane sulfonate without a template. This ‘fish-like’ unit grows repeatedly along the a direction into an infinitely extended one-dimensional silver multi-cluster. The inner silver was stabilized by the interaction of argentophilic Ag…Ag and peripheral Ag-S interaction. The structure and composition of the compound Ag20S20 were determined by single-crystal X-ray diffraction (XRD), Electrospray time-of-flight mass spectrometer (ESI-TOF-MS), Thermogravimetric analysis (TGA), and Fourier transform infrared spectroscopy (FT-IR). In addition, the solid-state UV-vis absorption spectra indicate that Ag20S20 is a wide bandgap semiconductor. Photocurrent test results demonstrate that Ag20S20 exhibits a favourable photocurrent response. |
