Abstract:A systematic investigation on the effect of alkyl length on the phosphorescence performances of all organic room-temperature alkoxy substituted benzil phosphors.
Three isomers (3Fmo, 3Fmm, 3Fmp) were synthesized with distinct luminescent properties. 3Fmm showed room-temperature phosphorescence due to unique π–π stacking, while 3Fmo and 3Fmp exhibited TADF. 3Fmo excelled in cellular imaging.

We report metal-free organic 1,2-diketones that exhibit fast and highly efficient room-temperature phosphorescence (RTP) with high colour purity under various conditions, including solutions. RTP quantum yields reached 38.2% in solution...
