High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

Molecular Design Strategies for High‐Voltage Organic Cathodes

Advanced Energy Materials, Volume 16, Issue 34, 9 September 2026.
This work proposes molecular engineering strategies for high‐voltage organic cathode materials for Li‐ion batteries: (1) increase Li‐O coordination number (CN), (2) achieve a greater increase in aromaticity upon reduction (∆Aromaticity), and (3) add an electron‐withdrawing group (EWG), through a combined experimental and computational study on reported

Role of the Bridge Length and Structure in Photoinduced Mixed‐Valence Systems

ChemPhotoChem, Volume 10, Issue 9, September 2026.
A longer analog of the excited‐state Creutz–Taube ion displays, despite a donor–acceptor distance of 1 nm, substantial electronic coupling in the MLCT excited state, facilitated by bridging‐ligand planarization upon transient reduction. This results in a two‐order‐of‐magnitude extension of the MLCT lifetime to around 3 ns, despite a rather localized ...

Effects of Different Drying Methods on the Meat Quality and Characteristic Flavor Compounds of Pacific White Shrimp

Food Frontiers, Volume 7, Issue 5, September 2026.
Different drying strategies regulated meat quality and characteristic flavor formation in Litopenaeus vannamei through distinct thermal and dehydration effects. HAFD enhanced non‐volatile umami compounds by promoting free amino acids, GMP, and EUC accumulation, whereas HAD and AFD intensified roasted‐aroma formation through pyrazines, aldehydes, esters,
