The invention discloses an organic semiconductor compound and an organic electroluminescence device using the compound, and relates to an organic light-emitting diode. The diode consists of a cathode, an anode and an organic semiconductor layer between the cathode and the anode; the organic semiconductor light-emitting layer contains an organic semiconductor compound which has a structural formula as shown in the description. The organic semiconductor compound is characterized in that an organic semiconductor consists of a heteroaromatic ring containing a benzene ring and a naphthalene ring with nitrogen atoms having electricity absorbing performance, wherein pyrrole ring nitrogen atoms are linked with a substituent group of expanded pi-conjugation or a linking group L1 of expanded molecular weight. The organic semiconductor is used as the light-emitting layer in application; the light-emitting efficiency can be improved; and the operating life of the device is prolonged.
