Halogenation of an electron acceptor in TADF emitters is presented as a feasible strategy for shortening the DF lifetimes of TADF emitters without sacrificing their photoluminescence quantum yields. A greenish-yellow device based on the chloride-substituted emitter (ClPPM) achieves a high external quantum efficiency of 22.2% and an ultra-slow efficiency roll-off of 12.3% at a practical luminance of 1000 cd m-2, which is comparable to the state-of-the-art device performance for green-to-yellow TADF OLEDs at the practical luminance. The results came from multiple reactions, including the reaction of 2,4,6-Trichloropyrimidine(cas: 3764-01-0Synthetic Route of C4HCl3N2)
2,4,6-Trichloropyrimidine(cas: 3764-01-0) is a member of organic chlorides. Organic chloride content in crude oil can be detected through specialized laboratory analysis. Care and attention are essential while sampling and testing.Synthetic Route of C4HCl3N2
