Abstract

We report the synthesis and characterization of new, user-friendly gold(I) [Au(μ-(NH)CCF)] coordination polymer and [AuCl(NH(NH=)CCF)] complex. These compounds were investigated for potential application as precursors in chemical vapor deposition (CVD) and focused electron/ion beam-induced deposition (FEBID/FIBID), which are additive methods to produce nanomaterials. Single-crystal X-ray diffraction, elemental analysis, and infrared spectroscopy were used to determine the complexes' composition and structure. We studied their thermal stability and volatility using thermal analysis and variable-temperature infrared spectroscopy (VT IR) and by conducting sublimation experiments. The gold(I) amidinate [Au(μ-(NH)CCF)] sublimates at 413 K under 10 mbar pressure. The electron-induced decomposition of the complexes' molecules in the gas phase and of their thin layers on silicon substrates was analyzed using electron impact mass spectrometry (EI MS) and microscopy studies (SEM/EDX), respectively, to provide insights for FEBID and FIBID precursor design. The [AuCl(NH(NH=)CCF)] hydrogen chloride molecules evolved during heating, with the formation of gold(I) amidinate. The obtained results revealed that the new gold(I) amidinate may be a promising source of metal for nanomaterial fabrication by gas-assisted methods.

摘要

我们报道了新型、用户友好型的金（I）[Au(μ-(NH)CCF)]配位聚合物和[AuCl(NH(NH=)CCF)]配合物的合成与表征。对这些化合物作为化学气相沉积（CVD）和聚焦电子/离子束诱导沉积（FEBID/FIBID）前驱体的潜在应用进行了研究，这两种方法是制备纳米材料的加成法。利用单晶X射线衍射、元素分析和红外光谱来确定配合物的组成和结构。我们通过热分析、变温红外光谱（VT IR）以及升华实验研究了它们的热稳定性和挥发性。金（I）脒基配合物[Au(μ-(NH)CCF)]在10毫巴压力下于413 K升华。分别使用电子轰击质谱（EI MS）和显微镜研究（SEM/EDX）分析了配合物分子在气相中以及在硅衬底上的薄层中的电子诱导分解，以便为FEBID和FIBID前驱体设计提供见解。加热过程中[AuCl(NH(NH=)CCF)]会释放出氯化氢分子，同时形成金（I）脒基配合物。所得结果表明，新型金（I）脒基配合物可能是通过气体辅助方法制备纳米材料的一种有前景的金属源。
