A luminescent material, particularly an organic luminescent material, containing a triarylamine derivative of formula (1):
wherein X represents an arylene group other than a phenylene group, or a divalent heterocyclic group other than a thienylene group; Ar1 and Ar2 independently and individually represent a phenylene group or a naphthylene group; and R1 through R20 independently and individually represent a hydrogen atom, a halogen atom, a C1-C6 alkyl group, a C1-C6 alkoxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, the substituted or unsubstituted aryl group or the substituted or unsubstituted heterocyclic group may be condensed with the corresponding benzen ring at an arbitrary position of the benzen ring. Also disclosed is an organic electroluminescent device (organic EL device) making use of the above compound. The organic electroluminescent device has a long service life and exhibits high luminous efficiency.
一种发光材料,特别是一种有机发光材料,包含公式(1)的三芳胺衍生物:其中X代表除苯基外的芳基基团或除噻吩基团外的二价杂环基团;Ar1和Ar2分别独立地代表苯基或萘基;R1至R20独立地代表氢原子、卤素原子、C1-C6烷基、C1-C6烷氧基、取代或未取代的氨基、取代或未取代的芳基或取代或未取代的杂环基团,所述取代或未取代的芳基或取代或未取代的杂环基团可以在苯环的任意位置与相应的苯环融合。还公开了利用上述化合物制成的有机电致发光器件(有机EL器件)。该有机电致发光器件具有长寿命和高发光效率。
