文摘

A robust and water-stable porous coordination polymer [Cd(NDC)_0.5(PCA)]路G_x (1) (H₂NDC = 2,6-napthalenedicarboxylic acid, HPCA = 4-pyridinecarboxylic acid, G = guest molecules) with new network topology has been synthesized solvothermally. The framework is 3D porous material and forms a 1D channel along the c-axis, with the channel dimensions 9.48 脳 7.83 脜². The compound has high selectivity in uptake of CO₂ over other gases (H₂, O₂, Ar, N₂, and CH₄). The framework is highly stable in presence of water vapor even at 60 掳C. The high CO₂ selectivity over other gases and water stability makes the compound promising candidate for industrial postcombustion gas separation application.
