Solution‐Processable, Ladder‐Branched Polyimides of Intrinsic Microporosity by [4+4] Cycloaddition for Membrane Gas Separation

Advanced Materials, EarlyView.
An effective post‐synthetic modification strategy utilizing [4+4] cycloaddition is demonstrated to fabricate ladder‐branched polyimides of intrinsic microporosity (PIM‐PIs) with significantly enhanced performance characteristics for membrane‐based gas separation.

Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

Advanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...
