Abstract

A novel flexible one-dimensional coordination polymer [Cu(3-OH-bza)(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 HO adsorption rate that is decelerated to a greater extent by CO than by N. Key to this phenomenon is the observation that 1 undergoes a structural change upon reversible and selective adsorption of HO. This finding serves as the basis of a new strategy for designing porous materials for highly efficient separation and storage applications.

摘要

一种新型的柔性一维配位聚合物[Cu(3-OH-bza)(AcO)(pyr)]（1，3-OH-bza = 3-羟基苯甲酸根，AcO = 乙酸根，pyr = 嘧啶）被发现以受共存气体性质影响的速率吸附水。当暴露于含有气体的水蒸气气流中时，1表现出的水吸附速率被CO减缓的程度比被N减缓的程度更大。这一现象的关键在于观察到1在可逆且选择性地吸附水后会发生结构变化。这一发现为设计用于高效分离和存储应用的多孔材料的新策略奠定了基础。
