Herein, we firstly report the precipitation–involved CO2 capture from ultradilute sources (e.g., exhaled gas and indoor air) and the reversible room–temperature CO2 release accelerated by mechanical power using a covalent organic superphane cage. This superphane based operating system enables CO2 in ultradilute gas (< 6%) to be concentrated up to 83%. As inferred from the control experiments and theoretical calculations, this proof–of–concept CO2 capture and concentration system with mechanical power–triggered CO2 release by the discrete organic cage could be rationalized by the formation of a six–membered ring transition state with relatively low energy barrier during the process of the adsorption and desorption of CO2 on the cage surface, along with the precipitation involved phase change.
