The Cover picture shows the dominance of the 1:1 reaction mechanism in the CO 2 capture by a proline‐based ionic liquid (IL). Elucidated by a quantitative analysis method, the proline‐based IL was the only IL in the study that adopted a predominantly 1:1 reaction mechanism with CO 2 , showing apparent equimolar absorption. The rigid ring‐structure around the amine group creates a unique electrostatic environment that inhibits the general 1:2 reaction mechanism seen in other ILs, which results in a higher CO 2 capacity. These results not only shed light on the practical reaction mechanism of amine with CO 2 in anionic environments, but also provide instructive clues for the design of efficient amine‐functionalized solvents and adsorbents for CO 2 capture and conversion. More details can be found in the Full Paper by Yang et al. on page 806 in Issue 8, 2016 (DOI: 10.1002/cssc.201501691).
