Abstract

The SO₂ adsorption–desorption capacity at room temperature and 1 bar of the metal–organic polyhedron MOP-CDC was investigated. In addition, the qualitative solid-state absorption–emission properties of this material (before and after SO₂ exposure) were measured and tested, and it demonstrated remarkable capability for SO₂ detection. Our results represent the first example of fluorimetric SO₂ detection in a MOP.
