    • An aromatic amine compound having a specific structure represented by the following formula (I); and an organic electroluminescent element comprising a cathode, an anode, and one or more organic thin film layers sandwiched between the electrodes and comprising at least a luminescent layer, wherein at least one of the organic thin film layers consists of the aromatic amine compound alone or contains the compound as a component of a mixture. Due to this constitution, the organic electroluminescent element emits light having any of various hues and has high heat resistance, long life, high luminance, and high luminescent efficiency. In particular, the organic electroluminescent element can be prevented from attenuating in luminance with the progress of operation. [In the general formula (I), Ar 1 to Ar 6 each independently is (un)substituted aryl whose nucleus has 6-20 atoms; and L 1 to L 3 each independently is a connecting group represented by the following general formula (II). {In the general formula (II), R 1 and R 2 each independently is hydrogen, etc., provided that R 1 and R 2 may be bonded to each other to form an (un)saturated ring.}]
    • 具有由下式(I)表示的具体结构的芳族胺化合物; 以及有机电致发光元件,其包含阴极,阳极和夹在所述电极之间的一个或多个有机薄膜层,并且至少包含发光层,其中所述有机薄膜层中的至少一个由单独的芳族胺化合物或 含有化合物作为混合物的组分。 由于这种结构,有机电致发光元件发射具有各种色调的光,并且具有高耐热性,长寿命,高亮度和高发光效率。 特别地,随着操作的进行,可以防止有机电致发光元件的亮度衰减。 [通式(I)中,Ar 1〜Ar 6各自独立地为具有6-20个原子的(未)取代芳基, 和L 1〜L 3各自独立地是由以下通式(II)表示的连接基团。 {在通式(II)中,R 1和R 2各自独立地是氢等,条件是R 1和R 2独立地是氢, SUP> 2可以彼此键合形成(未)饱和环。}]
