Blue host materials for organic light‐emitting diodes (OLEDs) based on silicon‐cored (tetraphenylsilane) anthracene derivatives are synthesized (see figure). These compounds, with a non‐coplanar molecular structure, have high glass‐transition temperatures and good amorphous‐film‐forming capabilities. When doped with a blue‐fluorescent dopant, blue emission with high color purity and high efficiency, up to 7.5 cd A −1 and 6.3%, is achieved.
