Coexisting gases regulate the rates of water adsorption by a flexible one-dimensional coordination polymer
A novel flexible one-dimensional coordination polymer [Cu<sub>2</sub>(3-OH-bza)<sub>3</sub>(AcO)(pyr)] (1, 3-OH-bza = 3-hydroxybenzoate, AcO = acetate, pyr = pyrimidine) was found to adsorb water at rates that are influenced by the nature of coexisting gases. Upon exposure to a flow of water vapor containing gas, 1 displays a H<sub>2</sub>O adsorption rate that is decelerated to a greater extent by CO<sub>2</sub> than by N<sub>2</sub>. Key to this phenomenon is the observation that 1 undergoes a structural change upon reversible and selective adsorption of H<sub>2</sub>O. This finding serves as the basis of a new strategy for designing porous materials for highly efficient separation and storage applications.
