Highly efficient nondoped OLEDs by using aggregation-induced delayed materials based on 10-phenyl-10H-phenothiazine 5,5-dioxide derivatives

Abstract

A novel electron acceptor based on 10-phenyl-10H-phenothiazine 5,5-dioxide (2PTO) was firstly introduced into construction of aggregation-induced delayed materials. The emitter PXZ2PTO contains phenoxazine as the electron donor, exhibiting both AIE characteristic and TADF properties. Due to the highly stereoscopic structure and small ΔEST of PXZ2PTO, a green nondoped TADF OLED realized a high maximum EQE, CE and PE of 16.4 %, 44.9 cd A-1 and 32.0 lm W-1 without using any optical outcoupling technology, respectively, which is comparable to the best reported nondoped TADF OLEDs. Besides, the efficiency of nondoped devices are comparable to the doped devices of PXZ2PTO with the maximum EQE, CE and PE of 16.3 %, 43.8 cd A-1 and 35.2 lm W-1, respectively.
