Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Advanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes

Advanced Materials, EarlyView.
This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for

Solvent‐Induced Structural Modulation in Nanoscale Covalent Organic Frameworks Enables High‐Performance NO2 Sensing

Angewandte Chemie, EarlyView.
Solvent intercalation disrupts the stacking order of protonated porphyrin‐based 2D COF nanoparticles, resulting in a less compactly packed structure with increased accessibility of porphyrin sites. This structural modulation leads to significantly enhanced chemiresistive NO2 sensing performance.
