“…Jou et al demonstrated five novel host materials ( ME4 , ME5 , ME9 , ME10 , and ME13 ) constructed with carbazole as the electron donor and sulfone or carbonyl as the electron acceptor (Scheme 3). 28 ME4 , ME5 , ME9 , ME10 , and ME13 had high E T values of 2.97, 2.62, 2.93, 2.98, and 2.61 eV, respectively. A green TADF emitter, 4CzIPN , was selected for fabricating OLEDs using a solution process, and the physical properties were studied.…”
