Diphenyl [4-(triphenylmethylsilyl) phenyl] phosphine oxide (TSPO1) has the structure of triphenylphosphine oxide and triphenylsilane. TSPO1 has a large dipolar moment due to polar phosphine oxide group and its asymmetric structure.TSPO1With higher triplet energy (E)T=3.36 eV), which can be used as fluorescent main body or exciton barrier layer material in TADF-OLED devices.TSPO1 has a lower one.LUMO (ELUMO=2.52 eV) energy level and high HOMO (EHOMO=6.79 eV) energy level, and the diphenylphosphine oxide fragment of TSPO1 is electron deficient, so it is also suitable for electron injection layer (EIL) and hole barrier (HBL).
