本文报道了Yb（III）和Nd（III）的三价稀土配合物的合成、X射线结构、溶液稳定性和物理性质。这些配合物采用四齿和八齿配体设计策略，并引入了1-甲基-3-羟基吡啶-2-酮（Me-3，2-HOPO）螯合基团。Yb（III）和Nd（III）配合物在近红外（NIR）区域都有发射带，并且这种发光在水溶液中得以保留（）。此外，配合物在水溶液中表现出非常高的稳定性（pYb ~ 18.8 - 21.9），使它们成为进一步开发作为近红外成像探针的良好候选物。对模型Gd（III）配合物的低温（77 K）电子物理测量结果进行了分析，得到了其电子结构，并与简化模型一价钠配合物在B3 LYP/6- 311 G ++（d，p）水平上的TD-DFT计算结果相吻合.
The synthesis, X-ray structure, solution stability, and photophysical properties of several trivalent lanthanide complexes of Yb(III) and Nd(III) using both tetradentate and octadentate ligand design strategies and incorporating the 1-methyl-3-hydroxy-pyridin-2-one (Me-3,2-HOPO) chelate group are reported. Both the Yb(III) and Nd(III) complexes have emission bands in the Near Infra-Red (NIR) region, and this luminescence is retained in aqueous solution (). Furthermore, the complexes demonstrate very high stability (pYb ~ 18.8 – 21.9) in aqueous solution, making them good candidates for further development as probes for NIR imaging. Analysis of the low temperature (77 K) photophysical measurements for a model Gd(III) complex were used to gain an insight into the electronic structure, and were found to agree well with corresponding TD-DFT calculations at the B3LYP/6-311G++(d,p) level of theory for a simplified model monovalent sodium complex.
