Electric Field‐Dependent Conductivity as Probe for Charge Carrier Delocalization and Morphology in Organic Semiconductors

Advanced Functional Materials, EarlyView.
Applying a high electric field to a doped organic semiconductor heats up the charge carrier distribution beyond the lattice temperature, enhancing conductivity. It is shown that the associated effective temperature can be used to extract the effective localization length, which is a characteristic length scale of charge transport and provides ...

Solution-Processable Graphene Oxide as an Efficient Hole Injection Layer for High Luminance Organic Light-Emitting Diodes [PDF]

, 2013
The application of solution-processable graphene oxide (GO) as hole injection layer in organic light-emitting diodes (OLEDs) is demonstrated. High luminance of over 53,000 cd m-2 is obtained at only 10 V. The results will unlock a route of applying GO in

2,4-Dibromonaphthalen-1-ol [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
In the essentially planar (r.m.s. deviation = 0.023 Å) title compound, C(10)H(6)Br(2)O, an intra-molecular O-H⋯Br hydrogen bond generates an S(5) ring. In the crystal, mol-ecules are linked by an ⋯O-H⋯O-H⋯O- C(2) chain extending along [100], which involves the same H atom that participates in the intra-molecular hydrogen bond.

Organometallic Precursor‐Induced Gradient Architecture on Multilayer Nanoporous Graphene Membranes for Precise Organic Solvent Nanofiltration

Advanced Functional Materials, EarlyView.
Alumina growth narrows surface pores and seals non‐selective defects, enhancing selectivity while preserving the nanoporous graphene architecture. Additionally, the deposition enables gradient‐controlled structural modification, with intergrown alumina acting as a physical cross‐linker that stabilizes the laminar structure.

Harnessing the Orientation of Columnar Discotic Liquid Crystals for Narrowband Blue Emission with Enhanced Out‐Coupling Efficiency Toward Improvement of SP‐OLEDs Performance

Advanced Functional Materials, EarlyView.
Solution‐processed OLEDs containing discotic liquid‐crystalline MR‐TADF emitters are reported. Supramolecular self‐assembly induces homeotropic columnar alignment, enforcing preferential horizontal orientation of the emitter transition dipole moment in spin‐coated films, which leads to an enhancement in the device light outcoupling efficiency while ...

Thermally Activated Delayed Fluorescence in Phase‐Separated Nanostructures

Advanced Functional Materials, EarlyView.
A supramolecular, phase‐separation driven strategy yields charge transfer (CT) complexes from alternating electron‐deficient pyromellitic diimide and electron‐rich 4,5‐dibromoveratrole. The resulting CT complexes self‐assemble into lamellar nanosheets with nanometer‐sized domains that exhibit thermally activated delayed fluorescence (TADF) at room ...
