Tuning the magneto-structural properties of non-porous coordination polymers by HCl chemisorption
Tuning the properties of responsive materials by applying an external stimulus could lead to their application as chemical switches or molecular sensors. Coronadoet al. develop a non-porous one-dimensional coordination polymer, the magnetic properties of which undergo drastic changes on chemisorption of gaseous HCl.
