有机电致发光元件
摘要：
本发明提供有机电致发光元件1，其在阴极(80)和阳极(20)之间至少含有发光层(50)和电子输送层(60)，电子输送层(60)含有下式(1)所示的化合物，发光层(50)含有由能隙2.8eV以下的下式(2)所示化合物构成的主体材料和由茚并苝衍生物构成的掺杂材料。A－B(1)(在此，A为碳环3个以上的芳香族烃基、B为可被取代的杂环基。)X－(Y)n(2)(在此，X为碳环3个以上的稠合芳香族环基、Y为选自取代或未取代的芳基、取代或未取代的二芳基氨基、取代或未取代的芳基烷基及取代或未取代的烷基的基团。n为1～6的整数，n为2以上时Y可以相同也可以不同。)
摘要（英）：

This invention provides an organic electroluminescent element 1 comprising at least a fluorescent layer (50) and an electron transport layer (60) provided between a cathode (80) and an anode (20). The electron transport layer (60) comprises a compound represented by formula (1), and the fluorescent layer (50) contains a host material of a compound represented by formula (2) having an energy gap of not more than 2.8 eV and a dopant material of an indenoperylene derivative. A-B (1) wherein A represents an aromatic hydrocarbon group having 3 or more carbon rings; and B represents an optionally substituted heterocyclic group. X-(Y) n (2) wherein X represents a condensed aromatic ring group having 3 or more carbon rings; Y represents a group selected from substituted or unsubstituted aryl groups, substituted or unsubstituted diarylamino groups, substituted or unsubstituted arylalkyl groups and substituted or unsubstituted alkyl groups; and n is an integer of 1 to 6, provided that, when n is 2 or more, Y's may be the same or different.
