TSPO1, fluorescent host or EBL material in TADF-OLED devices
Suitable for efficient electron injection and hole blocking
TSPO1, diphenyl[4-(triphenylsilyl)phenyl]phosphine oxide, has a structure of triphenylsilane connecting triphenyl phosphine oxide. Comparing with UGH-2, TSPO1 has large permanent dipole moment due to the polar phosphine oxide group and its asymmetric structure.
With a sufficiently high triplet energy (ET ) of 3.36 eV, TSPO1 can be used as fluorescent host or exciton blocking layer materials in TADF-OLED devices. Also with low lying LUMO (ELUMO = 2.52 eV) and HOMO (EHOMO = 6.79 eV), TSPO1 is suitable for efficient electron injection and hole blocking, owing to the electron deficient nature of diphenylphosphine oxide moiety it bears.
