Computational Study of Ignored Pericyclic Reactions: Rearrangements of 1,2‐Bis(Diazo)Alkanes to 1,2,3,4‐Tetrazines and Subsequent Fragmentations

Angewandte Chemie, EarlyView.
DFT calculations of the 8π‐electrocyclization of 1,2‐bis(diazo)alkanes and of other bis‐1,3‐dipoles reveal that this process can establish a so far ignored route to heterocycles such as 1,2,3,4‐tetrazines. Alternative reaction channels via carbenes or nitrenes leading to fragmentation products are discussed.

Beyond Density: Unveiling the Trade‐Off in Catalytic Site Optimization Using Defect‐Engineered UiO‐66

Advanced Science, EarlyView.
A well‐designed experimental model reveals a trade‐off between intrinsic activity and catalytic site density in performance optimization, due to inherent diffusion resistance arising from substrate adsorption at catalytic sites. Abstract Enhancing intrinsic activity and increasing catalytic site density are two widely employed strategies to improve ...

Structural Dependence of Catenand Effect: Thermodynamic and Kinetic Modulation of Catenane Coordination Properties via Ring‐size and Exocyclic Substituent Variation

Angewandte Chemie, EarlyView.
By modifying ring size and exocyclic substituents, effects of ligand interlocking on metal coordination features is explored. Through systematic analysis of CuI catenanes, relationship between structural parameters of the interlocked ligands and coordination properties like geometry, stability, and reactivity is established.

Acidogenesis‐Propelled Coordination Transition in Light‐Triggered Fe‐Polyphenol Polymer for Reactive Oxygen Species‐Augmented Antitumor Therapy

Advanced Science, EarlyView.
A novel iron‐polyphenol‐photoacid coordination polymer (FeBPs) is designed to achieve red light‐triggered external acidification and internal coordination regulation, where this light‐controlled acidification induces coordination changes that enhance Fe active site exposure and provide H+ for beneficial Fe3+/Fe2+ conversion, thereby accelerating ROS ...
