Degrees of Sulfonation: Mapping the Reactivity Landscape of Acridine and Acridone

Organics
Although sulfonated acridines and acridones are valuable scaffolds in diagnostics and materials science, to our best knowledge, there is no comprehensive study that addresses how the degree of sulfonation depends on reaction parameters. To fill this gap,

Excited State Modulation in Carbene‐Metal‐Amides to Design Fast and Bright Blue Delayed Fluorescence

Advanced Functional Materials, Volume 35, Issue 52, December 23, 2025.
Gold‐centered carbene‐metal amide (CMA) materials with carbonyl‐group substitution on the amide donor ligand. Molecular design ensures that the charge transfer (CT) state is lower in energy than the locally excited (3LE) states. The energy difference between CT and LE states controls the rate of the delayed fluorescence.

Through‐space interaction enables simultaneous enhancements of kr and kRISC in highly efficient spiro‐acridine based thermally activated delayed fluorescence emitter with acridone acceptor

Smart Molecules, Volume 3, Issue 4, December 2025.
Intramolecular through‐space interaction is designed for the first time in a thermally activated delayed fluorescence emitter to pull the appropriate rotation of the acridine donor to deviate from the perpendicular orientation, which solves the common problem of insufficient FMO overlap to simultaneously enhance the radiation transition and reverse ...
