It is an object of the present invention to provide a novel compound useful as a constituent of an organic EL element and the use of the compound permits the realization of a highly practical organic EL element whose driving voltage is substantially low and which has a low leakage current. Accordingly, the present invention herein provides a fluoranthene compound represented by the following general formula (1):
A-L-B (1)
wherein A and B each represent a monovalent group having a fluoranthene structure represented by the following general formula (2), provided that A is linked to the group L present in the general formula (1), at the carbon atom selected from those specified by the numerical values of 7 to 10 appearing in Formula (2) and that B is linked to the group L present in Formula (1), at the carbon atom selected from those specified by the numerical values of 1 to 6 appearing in Formula (2):
wherein L is a member selected from the group consisting of a single bond, substituted or unsubstituted arylene groups each having 6 to 40 carbon atoms, divalent groups derived from substituted or unsubstituted arylamines each having 6 to 40 carbon atoms, divalent groups derived from substituted or unsubstituted heterocyclic rings each having 3 to 40 carbon atoms and substituted or unsubstituted ethenylene groups.
本发明的目的是提供一种作为有机EL元件组分有用的新型化合物,该化合物的使用使得可以实现驱动电压实质上较低且具有低泄漏电流的高度实用的有机EL元件。因此,本发明在此提供一种由下述通用式(1)表示的芴烯化合物:
A-L-B (1)
其中A和B分别表示具有由下述通用式(2)表示的芴烯结构的一价基团,前提是A与通用式(1)中存在的L基团连接,在通用式(2)中出现的数值为7至10的碳原子中选择的碳原子上,并且B与通用式(1)中存在的L基团连接,在通用式(2)中出现的数值为1至6的碳原子中选择的碳原子上:
其中L是从以下组成的群体中选择的成员:单键,具有6至40个碳原子的取代或未取代芳基基团,由具有6至40个碳原子的取代或未取代芳胺衍生的二价基团,由具有3至40个碳原子的取代或未取代杂环戒指衍生的二价基团,以及取代或未取代乙烯基团。
