Abstract
We report a one-pot synthesis of 10-(diphenylphosphoryl)-anthracenes, featuring a rare multisubstitution on flanking rings with donor-acceptor groups (F, Br, CN, CF3, MeO, OCH2O) in 24-60% yields. Catalyzed by TMSOTf, the process involves a phosphinite-to-phosphine oxide rearrangement and cyclization. These emitters exhibit excellent photoluminescence quantum yields of up to 95% in both solution and solid states. Postsynthetic anthracene functionalization as well as the optoelectronic effect of substituents, particularly the Ph2P═O group, and the aggregation effect in solid on the photophysical properties, were also explored.

Abstract
An air-stable λ3-phosphinine-containing polycyclic aromatic compound without steric protection was synthesized and its charge transport properties were evaluated, which revealed moderate hole mobility. This research is the first experimental demonstration of the organic electronic applications of low-coordinate phosphorus compounds.

Abstract
Thermally activated delayed fluorescence (TADF) emitters have aroused considerable attention, particularly for their great potential in organic light-emitting diodes (OLEDs). In typical TADF molecules, intramolecular charge transfer (CT) between electron-donor (D) and electron-acceptor (A) moieties is the dominant transition. Actually, CT transitions can possibly occur between different molecules as well. Herein, we used a nonconjugated triptycene (TPE) moiety to space D and A moieties and developed two novel emitters tBuDMAC-TPE-TRZ and tBuDMAC-TPE-TTR to explore the roles of intra- and intermolecular CT transitions. Along with weak intramolecular CT transitions, intermolecular CT transitions are dominant for tBuDMAC-TPE-TRZ and tBuDMAC-TPE-TTR neat films. Particularly, tBuDMAC-TPE-TRZ showed a high maximum external quantum efficiency of 10.0% in a nondoped solution-processed OLED, which was evidently higher than that of a corresponding 10 wt % tBuDMAC-TPE-TRZ-doped OLED with 4,4',4″-tris(carbazol-9-yl)triphenylamine (TCTA) as the host matrix. The results prove that intermolecular CT transitions indeed participate in the CT transition process in these systems and they are helpful to enhance the electroluminescence performance of emitting systems with weak intramolecular CT transitions.
