Enhanced Thermodynamic Stability of UO22+ Complex Through Structure Preorganization of N3O2‐Pentadentate Planar Ligand for Uranium Harvesting from Seawater

Advanced Science, EarlyView.
Thanks to the appropriate structure preorganization of an N3O2‐pentadentate planar ligand, 2,6‐bis(2‐hydroxyphenylmethylaminomethyl)pyridine (H2saldamp) exhibits the strongest coordination affinity to UO22+ (log βU = 33.60) compared to ligands developed for uranium harvesting from seawater to date, as well as good separability of UO22+ from other metal

Spatial Control Over Tether‐Tunable Coordination on Palladium for Divergent Synthesis of Bicyclo[n.1.0]alkanes via Oxidative Cyclopropanation of Enynes

Advanced Science, EarlyView.
We have developed a Pd‐catalyzed oxidative cyclopropanation of 1,n‐enynes employing cyclic diacyl peroxides as bifunctional reagents that serve as both tether‐tunable oxidants and spatially controlled dicarboxylate anions. ABSTRACT Bicyclo[n.1.0]alkanes are highly valuable scaffolds in drug discovery and synthetic chemistry.

Meso‐Crowned Porphyrin as a Dual Cavity Hybrid Macrocycle for Improving the Efficiency and Stability of Perovskite Solar Cells

Advanced Science, EarlyView.
This study demonstrates a dual‐functional porphyrin‐based passivation molecule, [12]‐C‐4POR, capable of simultaneously coordinating Pb2+ and Li+ ions through its porphyrin core and crown ether moiety, respectively. This molecule effectively reduces trap‐state density, suppresses non‐radiative recombination, and mitigates Li+ migration at the perovskite/
