<p>Novel styryl compounds represented by the general formula (1) or (2); and an organic electroluminescent device with an organic compound film comprising at least a light emitting layer, wherein a novel styryl compound described above is contained in at least one layer constituting the film: (1) (2) (wherein R?1 to R10¿ are each independently hydrogen, alkyl, alkoxy, aryl, aryloxy, a fused polycyclic group, a heterocyclic group, amino, alkylamino, arylamino, cyano, nitro, hydroxyl, or halogeno, or alternatively any adjacent two of R?1 to R10¿ may be united to form a saturated or unsaturated carbon ring; and A, B, C, D, A', B', C' and D' are each independently a substituted or unsubstituted alkyl or aryl group having a specific structure). The invention provides organic electroluminescent devices exhibiting high heat resistance, high light emitting efficiency, long lifetime and high blue color purity, and novel styryl compounds capable of realizing such electroluminescent devices.</p> |
