Cover Feature: Pyrene‐Based “Turn‐Off” Probe with Broad Detection Range for Cu²⁺, Pb²⁺ and Hg²⁺ Ions (Chem. Eur. J. 31/2021)

Abstract

Sensing of metal contaminants in different environments is crucial for the control of pollution. A highly specific sensor for mercury, lead, and copper based on the interaction of pyrene‐based moieties functionalized at their 2‐position has been synthesized and characterized. The detection of fluorescence quenching of the monomer emission allows for a broad dynamic range and sensing is possible in organic solvents and in the presence of other cations such as Na+, K+, Ca2+, or Mg2+.
