研究目的
Investigating the synthesis and photophysical properties of lanthanide-based coordination polymers with 1,4-carboxyphenylboronic acid as ligand for potential application as multigauge luminescent thermometric probes.
研究成果
The study demonstrates the possibility to design multiemissive lanthanide-based coordination polymers that could find their application as multigauge luminescent thermometric probes. The anisotropic nature of the metallic distribution in the material makes the optical dilution by Gd3+ ions efficient, allowing for multiple emissions under a unique excitation wavelength.
研究不足
The study is limited to the synthesis and photophysical properties of lanthanide-based coordination polymers with 1,4-carboxyphenylboronic acid as ligand. Potential areas for optimization include the efficiency of intermetallic energy transfer and the sensitivity of the luminescent thermometric probes.
1：Experimental Design and Method Selection
Reactions in water of lanthanide chlorides with the sodium salt of 1,4-carboxyphenylboronic acid under ambient pressure and temperature.
2：Sample Selection and Data Sources
Lanthanide oxides (4 N) were purchased from AMPERE Company. Lanthanide chlorides were prepared according to established procedures.
3：List of Experimental Equipment and Materials
Single crystals were mounted on a Nonius Kappa CCD Bruker diffractometer and on a D8 Venture Bruker diffractometer. Luminescence spectra were recorded on a Horiba Jobin Yvon Fluorolog III fluorescence spectrometer.
4：Experimental Procedures and Operational Workflow
Precipitation immediately occurred after mixing stoichiometric amounts of a lanthanide chloride and the sodium salt of 1,4-carboxyphenylboronic acid in water. Precipitates were filtered, rinsed with water, and dried in air.
5：Data Analysis Methods
Crystal structures were solved by direct methods using SIR97 program and then refined with full matrix least-squares method based on F2 (SHELX97). Luminescence spectra were corrected for the instrumental response function.
