A Noble‐Metal‐Free Porous Coordination Framework with Exceptional Sensing Efficiency for Oxygen

Light material: By virtue of the unique framework structure and very high oxygen permeability, a noble-metal-free, highly fluorescent, porous coordination polymer demonstrates a rapid, reversible, efficient, stable, and selective fluorescence-quenching response toward oxygen.
