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 ...

Efficient Non‐Fullerene Acceptor‐Based Organic Photodetectors Achieved by Reduced Deep Traps in Highly Intermixed Co‐Evaporated Bulk‐Heterojunction Blends

Advanced Optical Materials, EarlyView.
Fullerene acceptor‐based organic photodetectors show sub‐optimal device performance due to deep trap states originating from undesirable adduct formation between donor and acceptor with unfavorable bulk‐heterojunction morphology. This work demonstrates subphthalocyanine‐based non‐fullerene acceptor (like Cl6‐SubPc) has great potential for trap‐free ...

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 ...

Communications platform payload definition study, executive summary [PDF]

Large geostationary communications platforms have been investigated in a number of studies since 1974 as a possible means to more effectively utilize the geostationary orbital arc and electromagnetic spectrum and to reduce overall satellite ...
