Abstract

A new NbO-type metal–organic framework ZJNU-40 incorporating highly polarized benzothiadiazole moieties exhibits a high CO₂ uptake of 108 cm³ g⁻¹ at 296 K and 1 atm, as well as good adsorption selectivities of CO₂ over CH₄ and N₂ at room temperature, which is superior to that of the analogous MOF NOTT-101.
