This invention discloses novel light-emitting materials. These materials comprise a side chain which contains at least two Si or Ge atoms, such as bis(trimethylsilyl)methyl, or a side chain that includes SiF bond, or a side chain that includes a fluorine-containing alkyl chain. This new side chain could fine tune emission color, reduce the stacking of the light-emitting materials, maintain good lifetime, and result in high PLQY.
