Hightripletenergyhostmaterialsbased on novel fused phenylcarbazole core structure and diphenylphosphine oxide were synthesized and the physical properties of the hostmaterials were investigated. A hightripletenergy of 2.95 eV was obtained from the fused phenylcarbazole basedhostmaterials and the energy levels could be manipulated using the diphenylphosphine oxide group. The fused phenylcarbazole
