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

摘要

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 photo-switchable diarylethene unit resulted in record C02-desorption capacity of 75% under static irradiation and 76% under dynamic irradiation.
