Borenium ions, originally synthesized as fundamentally important laboratory curiosities, have attracted significant attention due to their applications in catalysis and frustrated Lewis pair chemistry. However, investigations of the materials properties these types compounds are exceptionally rare. Herein, we report synthesis, molecular structures, optical a new class air-stable borenium stabilized by strongly donating carbodicarbene (CDC) ligand (2, 3, 6). Notably, CDC-borafluorenium ions...
Ytterbium-doped cesium lead halides are quantum cutting materials with exceptionally high photoluminescence yields, making them promising as scintillators. In this work, we report ytterbium-doped chloride (Yb3+:CsPbCl3) an X-ray scintillation light yield of 102,000 photons/MeV at room temperature, which is brighter than the current state-of-the-art commercial The was achieved based on a novel method synthesizing Yb3+:CsPbCl3 powders using water and low-temperature processing. combination...
Abstract Singlet fission, a process by which one singlet exciton is converted into two lower energy triplet excitons, sensitive to the degree of electronic coupling within molecular packing structure. Variations in can be detrimental formation and triplet–triplet separation, ultimately affecting harvesting triplets for electricity organic photovoltaic devices. Here, six phase‐pure structures 6,13‐bis(triisopropylsilylethynyl)pentacene (TIPS‐pentacene) with varying optoelectronic properties...
Achieving reproducible perovskite solar cell fabrication is crucial for making it a scalable technology. We demonstrate an automated gas quenching system to improve reproducibility at the lab-scale. use in situ photoluminescence monitor film formation as function of atmosphere glove box and find that antisolvent more sensitive lingering precursor solvents than method. observe better with because maintains consistent box. The process leads high performing devices are both batch researcher...
Water oxidation to dioxygen is an essential energy capture process in biological systems mediated by the oxygen-evolving complex. It continues attract interest as a half-reaction electrochemical water-splitting hydrogen and abiotic systems. There corresponding improving activity of nonprecious metal electrocatalysts for this reaction. One most well-known water catalysts amorphous cobalt oxide. This catalyst can operate at neutral pH with low overpotentials known continually reform under...

Perovskites were utilized as a tunable layer to control crystallization and preferential orientation of energetic material thin films.
High-performance scintillators are essential for medical imaging, security, high-energy physics, and other fields. Lead halide perovskites attractive materials ionizing radiation detection due to their high X-ray absorption, defect tolerance, charge carrier mobility. Today's scintillator expensive, typically grown as single crystals at temperatures, whereas can be processed in solution low allowing scalable, low-cost, large-area devices. We synthesize infrared-bandgap quantum-dot-doped that...
Crystallization above the solvent boiling point facilitates identification of a new precipitation dominant morphology during meniscus guided coating.
Herein, we evaluate Yb3+ doped CsPbCl3 as a bright ceramic scintillator material and investigate different doping amounts to elucidate its luminescence enabled by quantum cutting. We demonstrate that the host perovskite structure is maintained up 7% mole Yb3+, which produces light yield of 102,000 photons/MeV. show these polycrystalline scintillators can be pressed into pellet used for x-ray imaging with resolution approximately 0.1 mm. The combination high simple, inexpensive synthesis...
