摘要

铕金属有机骨架（Eu-PDA）对UO22+进行了高选择性识别。利用Eu-PDA独特的化学结构，使PDA向UO22+的能量转移成为可能，从而使UO22+的荧光高度上调。Eu-PDA探针对UO22+的特异性优于许多干扰物质，因为UO22+的本征辐射被触发。

Ultra-selective recognition of UO22+via triggering its intrinsic luminescence using a precisely designed europium metal–organic framework†

A novel method for highly selective recognition of UO₂²⁺ is proposed based on a [Eu(pyridine-2,5-dicarboxylic acid N-oxide)] (Eu-PDA) metal–organic framework. Benefiting from the unique chemical structure of Eu-PDA, energy transfer from PDA to UO₂²⁺ was enabled, resulting in the highly up-regulated fluorescence of UO₂²⁺. The Eu-PDA probe showed excellent specificity to UO₂²⁺ over numerous interfering species, as the intrinsic emissions of UO₂²⁺ were triggered.
