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.
我们在此展示了一条有前景的途径，通过紫外线和可见光触发低能量 CO2 捕获和释放。使用光敏二芳烯配体构建了光致变色二芳烯金属-有机骨架（DMOF）。源于框架运动的局部光致变色反应由可光致变色的二芳烯单元引起，导致在静态照射下记录到 75%的 CO2 解吸容量，在动态照射下记录到 76%的 CO2 解吸容量。
