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.
