Thermally stable high-triplet-energyholetransportmaterials based on 8H-indolo[3,2,1-de]acridine core (FPC) were synthesized and the device performances of FPC-based phosphorescentorganiclight-emittingdiodes (OLEDs) were investigated. The FPC-based holetransportmaterials showed a high triplet energy (above 2.90 eV) and high glass-transition temperature (above 140 °C). The FPC-based hole-transport
