Summary:It is found that aralkylamines solidified even in water by absorption of aerial CO2. Despite being amphiphilic, the aralkylamines absorbed CO2 and self‐assembled against the amphiphilicity to form a reverse lipid bilayer structure and solidified. Once the solid‐liquid separation of aerial CO2‐captured amines in water is achieved, it becomes possible to select the optimum conditions for both absorption and desorption. It is found that aralkylamines in water selectively absorbed aerial CO2 with the improvement of the CO2 absorption ability, and the resulting aralkylamine/CO2 complexes are solidified. Therefore, it is possible to release and concentrate the captured CO2 without external energy for water heating. In addition, it is detected that the solid‐state aralkylamine/CO2 complexes formed reverse lipid bilayer structures in the water against the affinity.
