Synthesis of fused phenylcarbazole phosphine oxide based high triplet energy host materials

High triplet energy host materials based on novel fused phenylcarbazole core structure and diphenylphosphine oxide were synthesized and the physical properties of the host materials were investigated. A high triplet energy of 2.95 eV was obtained from the fused phenylcarbazole based host materials and the energy levels could be manipulated using the diphenylphosphine oxide group. The fused phenylcarbazole based high triplet energy host materials showed excellent morphological stability at high temperature. High triplet energy host materials based on novel fused phenylcarbazole core structure and diphenylphosphine oxide were synthesized and a high triplet energy of 2.95 eV could be obtained from the host materials.
