We report MPM-1-TIFSIX, a molecular porous material (MPM) based upon the neutral metal complex [Cu2(adenine)4(TiF6)2], that self-assembles through a hydrogen-bonding network. This MPM is amenable to room-temperature synthesis and activation. Gas adsorption measurements and ideal adsorbed solution theory selectivity predictions at 298 K revealed enhanced CO2 separation performance relative to a previously known variant as well as the highest CO2 uptake and isosteric heat of adsorption yet reported for an MPM. MPM-1-TIFSIX is thermally stable to 568 K and retains porosity and capacity even after immersion in water for 24 h.
我们报告了 MPM-1-TIFSIX，这是一种基于中性金属配合物[Cu2(腺嘌呤)4(TiF6)2]的分子多孔材料 (MPM)，它通过氢键网络自组装。这种 MPM 易于在室温下合成和激活。在 298 K 下进行的气体吸附测量和理想吸附溶液理论选择性预测表明，与以前已知的变体相比，CO2 分离性能得到了增强，并且是迄今为止报道的 MPM 中 CO2 吸收量和等温热吸附量最高的。MPM-1-TIFSIX 在 568 K 下热稳定，即使在水中浸泡 24 小时后也能保持孔隙率和容量。
