<jats:title>Abstract</jats:title><jats:p>Immobilization and reuse of CO<jats:sub>2</jats:sub> are urgent tasks for sustaining the global environment. Here it is demonstrated that CO<jats:sub>2</jats:sub> can be immobilized by reaction with H<jats:sub>2</jats:sub>O at room temperature (RT) in the specific sub‐nm space of 1D uneven‐structured C<jats:sub>60</jats:sub> polymer (1D polymer) film, even though the reaction does not occur at RT in the gas phase (activation energy: 2 eV). First‐principles calculations reveal that the CO<jats:sub>2</jats:sub> molecule is stacked as a bridge between the concave portions of adjacent 1D polymer frameworks via locally induced Coulomb interactions. Such induced charge polarization activates CO<jats:sub>2</jats:sub> both by weakening its double‐bonds and by lowering its lowest unoccupied molecular orbital energy due to the bending motion. In addition, the flexible π orbitals of the 1D polymer provide the optimal Coulomb field to stabilize the transition state of the CO<jats:sub>2</jats:sub> + H<jats:sub>2</jats:sub>O reaction remarkably. These factors work together to make the reaction possible at RT.</jats:p>
