研究目的
Investigating the synthesis, structures, and fluorescent properties of a series of lanthanide coordination polymers based on a flexible bis-(imidazole-4,5-dicarboxylate) ligand.
研究成果
Five isomorphic lanthanide complexes with novel architectures have been prepared successfully under hydrothermal conditions. The flexible HL3? ligands bridge metal nodes through two IDC groups in different fashions to generate a 3D sra network. The efficient energy transfer from the HL3? ligands to the resonance level of lanthanide ions results in complexes 4 and 5 exhibiting intense characteristic luminescent properties of Eu(III) and Tb(III).
研究不足
The study focuses on the synthesis and characterization of lanthanide coordination polymers and their luminescent properties, but does not explore potential applications in depth.
