Summary
Two new coordination polymers containing lanthanide and manganese ions were synthesized. These materials show potential as luminescent probes for detecting zinc ions due to a significant increase in emission intensity.
Area of Science:
- Materials Science
- Inorganic Chemistry
- Coordination Chemistry
Background:
- Coordination polymers (CPs) are crystalline materials constructed from metal ions and organic ligands.
- Lanthanide-based CPs are of interest for their unique luminescent properties.
- Investigating heterometallic CPs can lead to novel functional materials.
Purpose of the Study:
- To synthesize novel 3d-4f heterometallic coordination polymers.
- To investigate the luminescent sensing capabilities of these CPs for metal ions.
Main Methods:
- Hydrothermal synthesis was employed to create the coordination polymers.
- Luminescence spectroscopy was used to study the response of the materials to various metal ions.
Main Results:
- Two 1D coordination polymers, {[Ln(PDA)3Mn1.5(H2O)3].3.25H2O}infinity (Ln = Eu, Tb), were successfully synthesized.
- The luminescence intensities of both Eu- and Tb-based CPs significantly increased upon the addition of Zn2+ ions.
- Other tested metal ions did not enhance or weakened the luminescence, indicating selectivity.
Conclusions:
- The synthesized coordination polymers exhibit selective luminescence enhancement in the presence of Zn2+.
- These materials show promise as selective luminescent probes for Zn2+ detection.
