银纳米簇二维组装体合成、发光与抑菌性能
Synthesis,luminescence,and bacteriostatic performance of Ag(Ⅰ)nanocluster 2D assembly
摘要
Abstract
Ag(Ⅰ)-S complex assemblies of two-dimensional(2D)sheet structure have good application prospects in luminescence,catalysis,and bacteriostatic performance.D-penicillamine is used as a capping agent to prepare Ag(Ⅰ)-S complex assembly by"one-pot"method at room temperature,which is in detail characterized by ATR-FTIR spectrum,X-ray photoelectron spectrum,NMR spectrum,elemental analysis,high-resolution mass spectrum,and thermogravimetric analysis.Transmission electron microscope,cryogenic-selected area electron diffraction,atomic force microscope,and powder X-ray diffraction analyses indicate that Ag(Ⅰ)-S complex assembly is a type of novel sheet structure comprised of Ag nanoclusters,in which the single sheet merely possesses a thickness of around 8.3 nm.The 2D Ag(Ⅰ)-S nanocluster assembly H[Ag5(DPA)6]shows intense green emission,and its absolute luminescent quantum yield is found to be as high as 10.6%,the photoluminescent lifetime at 540 nm is around 14.5µs,and thus the assembly luminescence is believed to arise from triplet ligand-to-metal-metal charge transfer transition(3LMMCT).The Ag(Ⅰ)nanocluster assembly of sheet structure can be formed only when the molar ratio of D-penicillamine and silver nitrate is larger than 2,which suggests that in this case Ag nanoclusters H[Ag5(DPA)6]can undergo oriented attachment with each other into close-packed sheet supramolecular assembly through Ag(Ⅰ)…Ag(Ⅰ)interactions and inter-ligand hydrogen bonds.In addition,the Ag(Ⅰ)-S assembly shows good bacteriostatic performance,which functions through the destroying of cellular membrane permeability,and has great application potentials in cosmetics area.Our work not only provides a good model for the construction of ultrathin 2D assembly and the investigation of luminescent and bacteriostatic behaviors but also offers significant guidance and reference for the design and construction of other 2D materials.关键词
