    摘要: An electroluminescent element has an anode, a cathode, and an organic layer structure between the two electrodes. The layer structure has a luminescent zone containing 1,9-perinaphtylene-10-1′-naphthylanthracene or derivatives as dopant. The luminescent material utilized as dopant has the following structure called pNNA or pNNA derivatives: Wherein: R1, R2, R3, R4 are individual substituents or a group of substituents, and they may be identical or different. Each substituent is individually selected from the following groups consisting of: H, alkyl (—R), halogen (—X), aryl (—Ar), alkenyl (RCH═CH—), allyl(CH2═CHCH2—), cyano (NC—), isocyano (CN—), amino (H2N—), tertiary amino (R2N—or Ar1Ar2N—), amide (RCONR—), nitro (N2O—), acyl (RCO—), carboxyl (—CO2H), alkoxyl (RO—), alkylsulfonyl (RSO2—), hydroxy (HO—) and single or fused aromatic heterocyclic rings.

    摘要: A low-voltage organic light-emitting device has a light-transmissive hole-injecting electrode on a light-transmissive substrate, and formed over the hole-injecting electrode, in sequence, an organic hole-transporting layer, an organic light-emitting layer, a bi-layer interfacial structure, an electron-transporting layer having an electron affinity higher than an electron affinity of the light-emitting layer, and an electron-injecting electrode. The bi-layer interfacial structure provides effective electron transport from the electron-transporting layer to the light-emitting layer.
