Carbene–Metal–Amide Materials Design: Tailoring π‐Extended Amides for High‐Performance Organic Light‐Emitting Diodes

Advanced Science, Volume 13, Issue 6, 30 January 2026.
Sky‐blue and green thermally activated delayed fluorescent emitters, carbene–gold–amides (CMA), possess near unity photoluminescent quantum yields and high radiative rates up to 2.1 × 106 s−1. Organic light‐emitting diodes (OLED) emit sky‐blue electroluminescence with efficiency over 20%, including host‐free OLED architecture, with operating stability ...

Discerning Blend Microstructure and Charge Recombination for Stable Biorenewable‐Based Organic Photovoltaics

Advanced Energy Materials, Volume 16, Issue 3, 21 January 2026.
A combination of morphological, electrical, and spectroscopy techniques is used to evaluate the degradation mechanisms of non‐fullerene (NFA)‐based organic photovoltaics (OPVs). Blends based on Y12 are more stable than Y6, aspeciallyOPVs from FO6‐T:Y12 demonstrated superior stability with an extrapolated T80 of over 2000 hours under maximum power point

Effect of Unique NNS Ligand in Manganese‐Catalyzed Transfer Hydrogenation Reaction—A DFT Mechanistic Study

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
The mechanism of transfer hydrogenation between isopropanol and acetophenone based on NN‐Mn(CO)3 and NNS‐Mn(CO)2 complexes has been computed. Both complexes have similar activity under mild conditions. Isopropanol dehydrogenation represents the rate‐determining step. Transfer hydrogenation has a much lower barrier than hydrogenation using molecular H2.
