Synthesis of Diaryl‐ and Dialkynylphosphinates From Ubiquitous PV Sources via a Redox‐Neutral Approach

Advanced Science, Volume 12, Issue 36, September 25, 2025.
Classical strategies for P─C bond formation rely on precursors (e.g., PH3, H2PO2, PCl3) obtained from P4, which is produced via the energy‐intensive thermal process. Here, an alternative, redox‐neutral approach is explored. Primary phosphate sources are activated with triflic anhydride (Tf2O) and 4‐dimethylaminopyridine (DMAP) to a versatile PV ...

New Wine in Old Bottles: Fully Substituted Arylthio Effect Realizes High‐Efficiency Purely Organic Phosphorescence Light‐Emitting Diode With Single and Ultra‐Stable Spectra Under 2000 cd m−2

Aggregate, Volume 6, Issue 4, April 2025.
Benefiting from the fully substituted arylthio effect, pure organic emitter 6S has the most obvious aggregation‐induced phosphorescence characteristic, the largest spin orbital coupling value, and the smallest the energy gap between S1 and T1. Consequently, a high maximum external quantum efficiency of 15.3% and ultra‐stable spectra under high ...
