Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

Advanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...

Resolving the Cu(bdc) Conundrum: Identifying Non‐Porous Packing of Prototypical Coordination‐Network Thin Films Combining Advanced Diffraction Techniques and Computational Modelling

Advanced Functional Materials, EarlyView.
Solution‐processed Cu(bdc) forms prototypical MOF thin films for which a multitude of not fully satisfactory structural models have been suggested. Combining rotating grazing‐incidence diffraction and X‐ray reflectivity on two complementary samples with density‐functional theory, we first discard the previously suggested models and then identify a non ...

Unraveling the Electronic Structure of Silicon Vacancy Centers in 4H‐SiC

Advanced Functional Materials, EarlyView.
The electronic structure of the silicon vacancy in 4H‐SiC is probed via transient absorption spectroscopy, uncovering previously inaccessible excited states of the quartet and doublet spin channels, including the V2' transition. In combination with theoretical analysis, a comprehensive picture of the electronic structure is established.
