Abstract

PCM-15 is a robust and recyclable sensor for the effective discrimination of a wide range of small molecules. Sensing is achieved by direct attenuation of the luminescence intensity of Tb(III) ions within the material. A competition study involving trace amounts of NH₃ in H₂ gas shows that PCM-15 can be used to quantitatively detect trace analytes.
