Vacuum‐Evaporated, Lead‐Free RbYbI3 Perovskite Interlayers for Universal Electron Injection in High‐Performance Organic Light‐Emitting Diodes

Advanced Materials, EarlyView.
ABSTRACT The optoelectronic performance of organic light‐emitting diodes (OLEDs) is critically governed by charge injection from electrodes into organic layers, where significant energy barriers at the interfaces often impede efficient charge injection.

Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

Advanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Suppressing Metal–Molecule Charge Transfer With a Phosphorus Interlayer

Advanced Materials Interfaces, EarlyView.
Phosphorus forms stable reconstructions with remarkable properties on various metal substrates. Here, using a spectroscopic approach, its role as an effective buffer layer on Cu(110) is demonstrated, preventing charge transfer to adsorbed Zn‐tetraphenylporphyrins (ZnTPP).

Phonon Engineering in Ultrathin Sn Films

Advanced Materials Interfaces, EarlyView.
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

Multifunctional Oxadiazole‐Based Polycatenars: A Pathway to Polar Columnar Phases

Advanced Materials Interfaces, EarlyView.
Aromatic core fluorination directs oxadiazole‐based polycatenars into ferroelectric and antiferroelectric columnar phases with supergelation and photo‐responsiveness. ABSTRACT Polar columnar liquid crystals (LCs) offer a promising pathway to nanostructured architectures for next‐generation ferroelectric devices.
