A 1,3,5-triazine derivative represented by formula (1):
wherein R
1
is hydrogen, C
1-4
alkyl group or substituted or unsubstituted phenyl group; n is an integer of 1-3, Ar is a substituted or unsubstituted aromatic hydrocarbon group, provided that Ar is different from two substituted quarterarylenyl groups bonded to the 1,3,5-triazine ring; and V and Y are nitrogen or carbon, provided that a case where both of V and Y are carbon atoms is excluded. The organic electroluminescent device comprising the 1,3,5-triazine derivative as an electron transport material has a long lifetime.
公式(1)所表示的是1,3,5-三嗪衍生物,其中R1是氢、C1-4烷基或取代或未取代的苯基;n是1-3的整数,Ar是取代或未取代的芳香族碳氢基团,但Ar不同于与1,3,5-三嗪环结合的两个取代季芳基基团;而且V和Y是氮或碳,但排除了V和Y均为碳原子的情况。将1,3,5-三嗪衍生物作为电子传输材料的有机电致发光装置具有长寿命。
