我们在此报道了一种刚性嵌套金属有机框架（MOF），其具有独特的温敏门控吸附行为，与任何已知的刺激响应性MOF的柔性模式相反，其取决于框架外抗衡离子的热运动。此外，该MOF还表现出在273 K下CO2对N-2，H-2和Ar的吸附选择性，从而实现CO2的战略分离和封装。
We herein report a rigid nested metal-organic framework (MOF) featuring a unique thermoresponsive gating adsorption behavior, which, in contrast to any known flexibility modes for stimuli-responsive MOFs, depends on the thermal motion of the extra-framework counterions. In addition, this MOF also exhibits adsorption selectivity of CO2 over N-2, H-2, and Ar at 273 K, thus enabling a strategic separation and encapsulation of CO2.
