Aggregation-induced emission (AIE) type thermally activated delayed fluorescent emitters (PTSOPO) were developed by asymmetric substitution of donor moieties to a diphenylsulfone acceptor. High QE of 17.7% was obtained in the doped PTSOPO device and the QE of the doped device was maintained in the nondoped
device by AIE effect, resulting in high QE of 17.0% in the non-doped device. Therefore, the asymmetric molecular design would be effectively used in the development of high efficiency non-doped device.
