研究目的
Investigating the aurophilicity and photoluminescence properties of (6-Diphenylpnictogenoacenaphth-5-yl)gold compounds.
研究成果
The study successfully synthesized and characterized a series of (6-diphenylpnictogenoacenaphth-5-yl)gold compounds, demonstrating significant aurophilic interactions and green-yellow photoluminescence in solution. The heterodinuclear gold complexes showed emission in the solid state, while the homodinuclear species were non-emissive. The findings contribute to the understanding of aurophilicity and photoluminescence in organogold chemistry, with potential applications in optoelectronics.
研究不足
The study is limited by the low photoluminescence quantum yields in solution and the non-emissive nature of some compounds in the solid state. The theoretical calculations are based on gas-phase geometries, which may not fully represent the solid-state or solution conditions.
1：Experimental Design and Method Selection:
The study involved the synthesis of organotin precursors and their conversion to organogold complexes through transmetalation reactions. The compounds were characterized using NMR spectroscopy, photoluminescence spectroscopy, and X-ray crystallography. Theoretical calculations including DFT and TD-DFT were performed to analyze the aurophilic interactions and photoluminescence properties.
2：Sample Selection and Data Sources:
The samples were synthesized from commercially available reagents and characterized using spectroscopic and crystallographic methods.
3：List of Experimental Equipment and Materials:
Bruker Avance-360 spectrometer for NMR, JASCO V-570 spectrometer for UV/Vis spectra, HITACHI F-4500 spectrometer for fluorescence spectra, Hamamatsu Photonics C9920-02G for photoluminescence quantum yields, and a Bruker Venture D8 diffractometer for X-ray crystallography.
4：Experimental Procedures and Operational Workflow:
The synthesis involved the preparation of organotin precursors, their conversion to organogold complexes, and subsequent characterization. The photoluminescence properties were studied in solution and solid state under different atmospheres.
5：Data Analysis Methods:
The data were analyzed using Gaussian09 for DFT and TD-DFT calculations, AIM2000 for topological analysis of electron density, and DGRID for ELI-D analysis.
