Pressure‐Activated and Retained Blue Emission in Melamine Through Hydrogen‐Bond and Packing Regulation

Advanced Science, EarlyView.
Pressure treatment activates and retains bright blue emission in melamine (MA). The pressure‐modified hydrogen‐bonding network and molecular packing create a distinct local environment after decompression, changing the balance among competing excited‐state relaxation pathways and enabling retained emission.

Solvent‐Desorption‐Induced Formation of a Long‐Period Polymorph Yielding a High‐Performance Porphyrin‐Based Organic Semiconductor

Advanced Science, EarlyView.
Solvent‐desorption‐induced structural transformation of 5,15‐bisphenyl‐tetrabenzoporphyrin generates a long‐period polymorph, in which the π‐stacking direction rotates by 90° between adjacent layers within the crystal while largely retaining crystallographic integrity.

Unlocking Zenith Electronic State of Ni Sites in Ligand‐Engineered COFs for Efficient •O2−‐Driven Uranium Photoreduction

Advanced Science, EarlyView.
We develop a ligand engineering strategy to construct Ni‐diketimine‐linked COFs with precisely tuned Ni electronic states. By varying the coordinated diketone units, we achieve an optimal electronic configuration that enhances O2 adsorption and lowers the energy barrier for •O2− generation.
