摘要

银(银)氨基化金属有机分解前体:[Ag2((ArN)2C(H))2] (Ar = 2,6-二甲基苯基(1),2,6-二乙基苯基(2)和2,6-二异丙基苯基(3))首次用于在具有多种功能的玻璃上沉积银薄膜,具有在光学/生物传感器或电子电路中的潜在应用。前驱体1-3以1:2的化学计量比从乙酸银与合适的配体反应中分离得到,并通过1H和13C{1H} NMR、热重分析和单晶x射线衍射对其进行了表征。在200°C的温度下,通过自旋涂层在玻璃基板上沉积单层,产生透明(>90%透过率)涂层,并具有良好定义的银纳米颗粒。在200°C下,多层沉积在玻璃上具有金属光泽,并且具有导电性能(ρ = 0.916-1.83 × 10−6 Ωm)。所有薄膜都具有很强的粘附性,并显示出对基材的良好覆盖。采用掠入射x射线衍射、x射线光电子能谱、能量色散x射线分析和扫描电镜对1 ~ 3号银膜进行了分析,并用紫外可见光谱测定了银膜的光学性质。

Deposition of metallic silver from versatile amidinate precursors for use in functional materials
Silver (Ag) amidinate metal organic decomposition precursors of the type: [Ag2((ArN)2C(H))2] (Ar = 2,6-dimethylphenyl (1), 2,6-diethylphenyl (2) and 2,6-diisopropylphenyl (3)) have been used for the first time in the deposition of Ag films on glass with multiple functionalities with potential application in optical/biological sensors or for use in electronic circuitry. Precursors 1–3 were isolated from the reaction of silver acetate with the appropriate ligand in a 1:2 stoichiometry and were characterized by 1H and 13C{1H} NMR, thermal gravimetric analysis and single crystal X-ray diffraction for 2. Single-layer depositions at 200 °C on glass substrates via spin coating produced transparent (>90% transmittance) coatings, with well-defined Ag nanoparticles. Multi-layer depositions at 200 °C on glass had a metallic lustre and were found to be conductive (ρ = 0.916–1.83 × 10−6 Ωm). All films were strongly adhered and displayed excellent coverage of the substrate. Ag films deposited from 1 to 3 were analysed by grazing incidence X-ray diffraction, X-ray photoelectron spectroscopy, energy-dispersive X-ray analysis and scanning electron microscopy, with optical properties determined by UV-Vis spectroscopy.

期刊介绍: The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
