The present invention discloses a new indenotriphenylene derivatives and an organic light emitting device using the derivative. The organic light emitting device employing the new indenotriphenylene derivative as host material can lower driving voltage, prolong half-lifetime, increasing efficiency. The new indenotriphenylene derivative is represented by the following formula(A):
According to formula(A), A1, A2 are substituted or unsubstituted aromatic ring systems with one to five rings and independently selected from the group consisting of a phenyl group, a naphthyl group, an anthracenyl group, a pyrenyl group, a chrysenyl group and a perylenyl group. R1 to R4 are identical or different. R1 to R4 are independently selected from the group consisting of a hydrogen atom, a halide, an alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 30 carbon atoms and a substituted or unsubstituted heteroaryl group having 6 to 30 carbon atoms. X is selected from carbon atom or nitrogen atom.
本发明揭示了一种新的茚三苯衍生物及其在有机发光器件中的应用。采用新的茚三苯衍生物作为主体材料的有机发光器件可以降低驱动电压,延长半衰期,提高效率。新的茚三苯衍生物由以下公式(A)表示:根据公式(A),A1、A2是具有1到5个环的取代或未取代芳香环系统,可独立地选自苯基、萘基、蒽基、芘基、蒽醌基和苝基。R1到R4相同或不同,可独立地选自氢原子、卤素、具有1到20个碳原子的烷基、具有6到30个碳原子的取代或未取代芳基、具有6到30个碳原子的取代或未取代芳基烷基、以及具有6到30个碳原子的取代或未取代杂环芳基。X选自碳原子或氮原子。
