摘　　要：Nowadays, purely organic materials with delayed fluorescence （DF） are being enthusiastically developed and extensively utilized as light-emitting materials to fabricate OLEDs because of their high exciton utilization and metal-flee nature. These DF materials usually have a small single-triplet splitting （AEsT）, and the nonradiative triplet excitons （75%） can be converted into radiative singlet excitons via thermally promoted reverse intersystem crossing （RISC） processes,Nowadays,purely organic materials with delayed fluorescence(DF)are being enthusiastically developed and extensively utilized as light-emitting materials to fabricate OLEDs because of their high exciton utilization and metal-free nature.These DF materials usually have a small single-triplet splitting(ΔEST),and the nonradiative triplet excitons(75%)can be converted into radiative singlet excitons via
