Solidification of Aerial CO2‐Captured Aralkylamines in Water Triggered by Self‐Assembly Against Affinity for Formation of Reverse Lipid Bilayer

Abstract

Abstract 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.
