Abstract We demonstrate herein a promising pathway towards low‐energy CO 2 capture and release triggered by UV and visible light. A photosensitive diarylethene ligand was used to construct a photochromic diarylethene metal–organic framework (DMOF). A local photochromic reaction originating from the framework movement induced by the photoswitchable diarylethene unit resulted in record CO 2 ‐desorption capacity of 75 % under static irradiation and 76 % under dynamic irradiation.
