title: Highly selective and responsive visible to near-IR ytterbium emissive probe for monitoring mercury(II).
abstract: A new lanthanide probe based on the fluorescence resonance energy transfer (FRET) process with the combination of ytterbium porphyrinate complex and a rhodamine B derivative unit was synthesized to detect the Hg(2+) ion with responsive emission in the visible and near-IR region with a detection limit of 10 μM.
