Microcrystalline 1D coordination polymers 1–3Pwd are able to adsorb vapours of chlorinated volatile organic compounds (Cl-VOCs), displaying interesting selectivity patterns, as demonstrated by 1H-NMR and X-ray diffraction analyses. Due to their dynamic breathing-like behavior, chemical and thermal stabilities and adsorption selectivity, these isostructural coordination polymers are promising to be used as filters for toxic Cl-VOCs.
