"4 boron-, nitrogen-containing multi-resonant thermally activated delayed fluorescence compounds performed as well or better. than scarce, costly, toxic catalysts like ruthenium, iridium... strong absorption in light, relative insensitivity of their excited states to solvent polarity, electron-rich make them strongly photoreducing photocatalysts... pinacol coupling, dehalogenation, E/Z isomerization reactions...avoids trace metal contamination in final product... pharmaceutical, agrochemical"
