PURPOSE: An electroluminescent device with arylethylene derivatives in hole transport layer is provided for an organic compound outsides the class of aromatic amines as a hole transport layer in organic electroluminescent device CONSTITUTION: An organic multilayer electroluminescent device including an anode and cathode, and comprising therebetween a hole transport layer and an electron transport layer disposed in operative relationship with the hole transport layer. The hole transport layer includes an organic compound having the formula. Wherein n is integer from 1 to 6; substituents R¬1 and R¬2 are each individually hydrogen, or alkyl of from 1 to 24 carbon atoms; aryl or substituted aryl of from 5 to 28 carbon atoms; heteroaryl or substituted heteroaryl of from 5 to 28 carbon atoms; F, Cl, Br, cyano group and R¬3 and R¬4 are each individually hydrogen, or alkyl of from 1 to 24 carbon atoms; aryl or substituted aryl of from 5 to 28 carbon atoms; heteroaryl or substituted heteroaryl of from 5 to 28 carbon atoms.
