Abstract

original image

Tetraphenylmethane and tetraphenylsilane were compared as building units for high-triplet-energy, charge-transport materials. Tetraphenylsilane is effective as the building unit in electron-transport materials, whereas tetraphenylmethane is suitable in hole-transport materials (see figure; TSPO1=diphenylphosphine oxide-4-(triphenylsilyl), TSPA=phenyl-N,N-diphenyl-4-(triphenylsilyl)aniline, and TCPA=N,N-diphenyl-4-tritylaniline).
