Photoswitching CO2 Capture and Release in a Photochromic Diarylethene Metal-Organic Framework

We demonstrate herein a promising pathway towards low‐energy CO2 capture and release triggered by UV and visible light.

Description
Summary:We demonstrate herein a promising pathway towards low‐energy CO2 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 CO2‐desorption capacity of 75 % under static irradiation and 76 % under dynamic irradiation. Low‐energy CO2 capture and release was possible with a metal–organic framework containing a photosensitive diarylethene ligand. The local framework flexibility caused by the photoswitchable diarylethene ligand (see picture) led to a record high CO2‐desorption capacity of 75 % under static irradiation and 76 % under dynamic irradiation.
