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).
