Abstract We demonstrate herein a promising pathway towards low‐energy CO 2 capture and release triggered by UV visible light. A photosensitive diarylethene ligand was used to construct photochromic metal–organic framework (DMOF). local reaction originating from the movement induced photoswitchable unit resulted in record ‐desorption capacity of 75 % under static irradiation 76 dynamic irradiation.
Reversible single-crystal-to-single-crystal transformation (SCSC) was for the first time observed between 4f-based molecular magnets.
Abstract Luminescent inorganic photochromics have great potential applications in 3D optical memory due to their excellent thermal stability and chemical resistance. Nevertheless, constructing with a high luminescence switching contrast remains challenging for information storage. Understanding inherent relationships between microenvironment changes, photophysical material properties, rational control of properties are crucial address these issues. This paper proposes an effective strategy...
