A new strategy for CO capture is reported based on the synergistic effect of electrostatic in-plane and dispersive π-π-stacking interactions of amide and indole with CO. Density functional theory illustrated that the amide group can have an increased ability to capture CO molecules that were just desorbed from an adjacent indole unit. We used this strategy to fabricate a microporous aerogel that exhibited a superior CO capture performance in both dry and wet conditions. The proposed synergistic effect is expected to be a new rationale for the design of CO capture materials.
报道了一种基于酰胺和吲哚与 CO 的静电面内和分散 π-π 堆积相互作用协同效应的 CO 捕获新策略。密度泛函理论表明，酰胺基团可以增强对刚刚从相邻吲哚单元解吸的 CO 分子的捕获能力。我们利用这一策略制备了一种微孔气凝胶，在干燥和潮湿条件下均表现出优异的 CO 捕获性能。预期这种协同效应为 CO 捕获材料的设计提供了新的依据。
