An anthracene derivative represented by the following general formula (1) which enables an organic electroluminescence device to exhibit a great efficiency of light emission and uniform light emission even at high temperatures since crystallization is suppressed and no thermal decomposition takes place during vapor deposition and an organic electroluminescence device utilizing the derivative, are provided.
[Ar represents a group represented by the following general formula (2):
(L1 and L2 each represent a substituted or unsubstituted methylene group, ethylene group or the like, and at least one of them is present), Ar' represents a substituted or unsubstituted aryl group having 6 to 50 nuclear carbon atoms, X represent an alkyl group or the like, a and b each represent an integer of 0 to 4, and n represents an integer of 1 to 3.]
本发明提供了由以下通式(1)表示的
蒽衍
生物和利用该衍
生物的有机电致发光器件,前者由于在气相沉积过程中结晶被抑制且不发生热分解,因此即使在高温下也能表现出很高的发光效率和均匀的发光。
[Ar 代表由以下通式(2)表示的基团:
(L1和
L2各自代表取代或未取代的亚甲基、
乙烯基或类似基团,且至少存在其中一个),Ar'代表具有6至50个核碳原子的取代或未取代的芳基,X代表烷基或类似基团,a和b各自代表0至4的整数,n代表1至3的整数]。
