Light-swing CO2 Capture: Photoirradiation-based Chemical CO2 Release Based on Photoisomerization of Azobenzene-Amine/Guanidine Derivatives

Azobenzene-amine/guanidine derivatives exhibit a light-swing method enabling CO 2 release under light irradiation with photoisomerization as the driving force. This method can selectively absorb CO 2 in air and release CO 2 by blue-light irradiation.
