Concentrating immiscible molecules at solid@MOF interfacial nanocavities to drive an inert gas-liquid reaction at ambient conditions

Gas‐liquid reactions form the basis of our everyday lives, yet they still suffer poor reaction efficiency and are difficult to monitor in situ, especially at ambient conditions. Herein, we drive an inert gas‐liquid reaction between aniline and CO2 at 1 atm and 298 K by selectively concentrating thes...
