Abstract
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.
