Trigonal Phosphine Umpolung: Electrophilicity Driven by a Redox‐Active Boron Cluster

Chemistry – A European Journal, EarlyView.
Coupling of a phosphine to a redox‐active cluster enables polarity reversal, or umpolung, at phosphorus. Phosphines are classically known for their nucleophilicity, and while electrophilic reactivity has been observed in geometrically constrained, non‐trigonal systems, similar behavior in ordinary trigonal phosphines is rare.

o‐Carborane‐based multi‐resonance thermally activated delayed fluorescence emitter exhibits highly efficient and multifunctional electroluminescence

FlexMat, EarlyView.
By strategically incorporating boron/nitrogen multi‐resonance (B/N‐MR) core into the o‐carborane unit, perfect exciton utilization can be achieved as well as exhibiting stimuli‐responsive properties. The resulting DBN‐oCb‐based organic light‐emitting diode (OLED) demonstrated an impressive external quantum efficiency of 22.3%, the highest reported for ...

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, EarlyView.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...
