Abstract

The synthesis, characterization, and photophysical properties of two novel ligands, 5LINMe-1,2-HOPO (1) and H(2,2)-1,2-HOPO (2), which utilize the 1,2-HOPO chelate as a sensitizer for Eu(III) are reported. In addition, the former ligand was structurally characterized as the Eu(III) complex by X-ray crystallography. The [Eu(1)2]- complex of the tetradentate ligand (1) is stable in aqueous solution, to a limiting concentration of ca. 7x10(-9) M, and retains the superior photophysical performance noted for the 1,2-HOPO sensitizer. By contrast, the octadentate ligand (2) has vastly improved stability as the [Eu(2)]- complex upon further dilution, to a limiting concentration of ca. 5x10(-17) M, which is beyond the minimum detectable concentration of most fluorimeters. The presence of a single coordinated water molecule for the latter complex reduces the overall metal-centered luminescence.

摘要

报道了两种新型配体5LINMe - 1,2 - HOPO（1）和H(2,2) - 1,2 - HOPO（2）的合成、表征及光物理性质，它们利用1,2 - HOPO螯合物作为Eu(III)的敏化剂。此外，通过X射线晶体学对前一种配体的Eu(III)配合物进行了结构表征。四齿配体（1）的[Eu(1)₂] - 配合物在水溶液中稳定，极限浓度约为7×10⁻⁹ M，并保留了1,2 - HOPO敏化剂所具有的优异光物理性能。相比之下，八齿配体（2）作为[Eu(2)] - 配合物在进一步稀释后稳定性大幅提高，极限浓度约为5×10⁻¹⁷ M，这超出了大多数荧光计的最低可检测浓度。后一种配合物中单个配位水分子的存在降低了整体以金属为中心的发光。
