研究目的
To synthesize and characterize a new zinc(II) complex with 2,6-pyridinedicarboxylic acid radical and 1,10-phenanthroline, and study its crystal structure and luminescent properties.
研究成果
The synthesized zinc(II) complex exhibits a distorted octahedral coordination geometry and strong fluorescence emission at around 367 nm in methanol solution, indicating potential applications in luminescent materials.
研究不足
The study is limited to the synthesis and characterization of a specific zinc(II) complex. The fluorescence properties were only tested in methanol solution, and the thermal stability was not fully explored beyond 700 °C.
1：Experimental Design and Method Selection
The complex was synthesized by reacting zinc sulfate, 2,6-pyridinedicarboxylic acid, and 1,10-phenanthroline in a mixed solvent of C2H5OH/H2O. The resulting solution was filtered and kept at room temperature for crystallization.
2：Sample Selection and Data Sources
Colorless block crystals suitable for X-ray diffraction were obtained. Elemental analysis, IR, UV-visible, TG, and X-ray single-crystal diffraction were used for characterization.
3：List of Experimental Equipment and Materials
Vario E1 elementar for elemental analyses, Nicolet 5700 FT-IR spectrophotometer for IR spectra, Lambda 650s UV-visible spectrophotometer for UV-visible spectra, Netzsch STA 449C thermal analyzer for TG analysis, CARY Eclipse fluorescence spectroscopy for fluorescence property testing, Bruker SMART APEX-II CCD diffractometer for X-ray crystallographic determination.
4：Experimental Procedures and Operational Workflow
The synthesis involved dissolving the ligands and NaOH in a mixed solvent, adding ZnSO4·7H2O, stirring, filtering, and allowing the filtrate to crystallize. Characterization techniques were applied to the obtained crystals.
5：Data Analysis Methods
The structure was solved by direct methods using SHELXS-97 program and refined with SHELXL-97 by full-matrix least-squares techniques on F2. Fluorescence spectra were analyzed for emission properties.
