研究目的
To synthesize and characterize a new coordination polymer based on cadmium(II) ions and flexible dicarboxylate and dipyridyl ligands, and to investigate its structural topology and photoluminescence properties.
研究成果
The study successfully synthesized a new 3D CdII coordination polymer with a rare (4,5)-connected binodal framework. The flexibility of the organic ligands played a crucial role in determining the final structure. The compound exhibits photoluminescence properties, suggesting potential applications in photochemistry and electroluminescent displays.
研究不足
The study focuses on the synthesis and characterization of a single coordination polymer. The photoluminescence properties are preliminary and may require further investigation to understand the mechanisms fully.
1：Experimental Design and Method Selection:
The coordination polymer was synthesized under hydrothermal conditions using Cd(NO3)2·4H2O, 4,40-oxydibenzoic acid (4,40-H2OBB), and trans-1,2-bis(pyridin-3-yl)ethene (3,30-BPE). The structure was characterized by IR spectroscopy, elemental analysis, and single-crystal X-ray diffraction analysis.
2：Sample Selection and Data Sources:
The samples were prepared by hydrothermal synthesis, and data were collected using single-crystal X-ray diffraction.
3：List of Experimental Equipment and Materials:
Nicolet Avatar 360 FT–IR spectrophotometer for IR analysis, EA1110 CHNS elemental analyzer for elemental analysis, PerkinElmer TGA-7 thermogravimetric analyser for thermal analysis, JASCO FP-8600 spectrofluorometer for fluorescence spectra.
4：Experimental Procedures and Operational Workflow:
The reactants were loaded into a Teflon-lined autoclave, heated, and then cooled to ambient temperature to produce crystals.
5：Data Analysis Methods:
The crystal structure was solved and refined using SHELXT and SHELXL2014, respectively. The topological analysis was performed using DIAMOND.
