We report a one-pot synthesis of 10-(diphenylphosphoryl)-anthracenes, featuring a rare multisubstitution on flanking rings with donor-acceptor groups (F, Br, CN, CF, MeO, OCHO) 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 PhP═O group, and the aggregation effect in solid on the photophysical properties, were also explored.
我们报道了一种一锅法合成10-(二苯基磷酰基)蒽的方法,其侧环上带有供体-受体基团(F、Br、CN、CF、MeO、OCHO)的罕见多取代产物,产率为24-60%。在三甲基甲磺酸镱(TMSOTf)催化下,该过程涉及亚膦酸酯到氧化膦的重排和环化。这些发光体在溶液和固态中均表现出高达95%的优异光致发光量子产率。还探索了合成后蒽的功能化以及取代基的光电效应,特别是PhP═O基团,以及固态中的聚集效应对光物理性质的影响。
