    摘要: An organic electroluminescence device (1) includes an anode (10), an emitting layer (20), an electron transporting zone (70), and a cathode (50) in sequential order. The emitting layer (20) includes a host and a fluorescent dopant. A blocking layer (30) is adjacent to the emitting layer (20) in the electron transporting zone (70). The blocking layer (30) includes an aromatic heterocyclic derivative. A triplet energy ET b (eV) of the aromatic heterocyclic derivative is larger than a triplet energy ET h (eV) of the host. The aromatic heterocyclic derivative has an azine ring.
