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