Multifunctionality and cytotoxicity of a layered coordination polymer

Area of Science:

• Materials Science
• Inorganic Chemistry
• Nanotechnology

Background:

• Coordination polymers offer tunable properties for diverse applications.
• Lanthanide-based materials are of interest due to their unique optical and catalytic properties.

Purpose of the Study:

• To synthesize and characterize novel 2D layered lanthanide coordination polymers.
• To investigate the catalytic, photoluminescent, and cytotoxic properties of these materials.

Main Methods:

• Synthesis via hydrothermal reaction, microwave-assisted synthesis, and one-pot methods.
• Characterization of crystal morphology and structure.
• Evaluation of catalytic activity in styrene oxide ring opening.
• Photoluminescence spectroscopy.
• Preliminary cytotoxicity assays on HK-2 and HepG2 cell lines.

Main Results:

• Successfully synthesized [Ln2(H3nmp)2]·xH2O coordination polymers (Ln = Sm, Eu, Tb, Dy, Ho, Er, Y).
• Achieved high catalytic conversion (88%/100%) and selectivity (100%) for styrene oxide ring opening.
• Observed promising UV-to-visible light conversion properties with long luminescence lifetimes for Eu-containing samples.
• Demonstrated minimal cytotoxicity towards HK-2 and HepG2 cells, with some impact on lysosomal activity.

Conclusions:

• The synthesized 2D layered lanthanide coordination polymers exhibit significant potential for heterogeneous catalysis and optoelectronic applications.
• The materials display tunable properties based on synthesis conditions and lanthanide composition.
• Further investigation into their biological interactions and advanced applications is warranted.
