TADF Emission in Supramolecular Assemblies through Cooperativity and Polymorphism

Advanced Optical Materials, EarlyView.
Macroscopic self‐assembled fibers emitting orange color with thermally activated delayed fluorescence (TADF) character are obtained by using encumbered phenyl D‐A linkers in a D‐A‐D configuration. The new dye self‐assembles through a cooperative mechanism into fibers that emit light upon electrical stimulus in solution‐processed organic light‐emitting ...

Research Progress on Benzimidazole Fungicides: A Review

Molecules
Benzimidazole fungicides are a class of highly effective, low-toxicity, systemic broad-spectrum fungicides developed in the 1960s and 1970s, based on the fungicidal activity of the benzimidazole ring structure.

Engineering Spontaneous Orientation Polarization in Blends of Polar Organic Semiconductors

Advanced Optical Materials, EarlyView.
Spontaneous orientation polarization (SOP) in organic semiconductor thin films can be modulated through molecular blending. A nonpolar dopant disrupts anti‐parallel dipole alignment in a polar host, promoting enhanced dipole orientation. Meanwhile, polar‐polar blends can retain their original dipole alignment, resulting in a linear GSP slope trend ...

Polarized Heterojunction in a Doubly Doped Layer‐by‐Layer Structure to Obtain an Organic Photovoltaic Device of 20.5% Efficiency

Angewandte Chemie, EarlyView.
A solvent‐mediated infiltration doping strategy was proposed, enabling efficient double doping in organic photovoltaics. By spatially separating F4TCNQ and DMBI dopants within a D18/L8‐BO layer‐by‐layer architecture, dopant crosstalk and trap formation are minimized by controlling the penetration depth.

Unlocking Spin Dynamics: Spin‐Orbit Coupling Driven Spin State Interconversion in Carbazole‐Containing TADF Emitters

Advanced Optical Materials, EarlyView.
This study explores overlapping charge transport mechanisms in TADF materials and identifies spin‐orbit coupling as the dominant mechanism for triplet‐to‐singlet transition in carbazole‐based cyanoarene emitters. Computational investigations reveal a second spin‐orbit‐coupling‐mediated reverse intersystem crossing pathway, significantly enhancing the ...

From CO2 to C1 Liquid Fuels: Molecular Electrochemical Production of Formic Acid and Methanol

Angewandte Chemie, EarlyView.
Sustainable transformation of CO2 into formic acid and methanol is key to circular carbon economies and sustainable energy. These liquid C1 products are high in energy density, easy to store, and serve as hydrogen carriers and feedstocks. Electrochemical CO2 reduction provides a promising route for carbon recycling and renewable energy integration ...

Synthesis, Characterization and Biological Evaluation of 1, 2-Disubstituted Benzimidazole Derivatives using Mannich Bases

E-Journal of Chemistry, 2010
The ring system in which a benzene ring is fused to the 4,5-positions of imidazole is designated as benzimidazole. Condensations of 2-substituted benzimidazole derivatives were synthesized by different carboxylic acids using Mannich base and anti ...

CCDC41 Drives Oocyte Meiotic Progression by Promoting Rab11a/Rab7‐Positive Vesicle Fusion with Target Membranes

Advanced Science, EarlyView.
CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,

Lead‐Free Tin‐Based Perovskite LEDs Toward Rec. 2020: Organic Anion Coordination for Oxidation Suppression

Advanced Science, EarlyView.
This study introduces an organic anion‐coordination for oxidation suppression (OCOS) strategy using alkali metal–organic anions (e.g., KEtO) to stabilize Sn2+ in lead‐free Sn‐based perovskites for PeLEDs. By coordinating with Sn2+ and inhibiting vacancies, OCOS enhances film quality, EQE (to 10.01% at 638 nm), and luminance (to 139.9 cd m−2 ...
