The present invention provides a stable new condensed polycyclic compound which is not likely to form a molecular association. In addition, the present invention also provides an organic light-emitting element having a high light-emitting efficiency and a low drive voltage. In the condensed polycyclic compound in Claim 1 represented by the general formula [1], R1, R2 and R5 are each independently selected from a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an aryl group, and a heterocyclic group. R3 and R4 each represent an alkyl group having 1 to 4 carbon atoms. The aryl group and the heterocyclic group each may have at least one of an alkyl group, an aralkyl group, an aryl group, a heterocyclic group, an amino group, and an alkoxy group as a substituent.
本发明提供一种稳定的新型稠环化合物,不太可能形成分子缔合物。此外,本发明还提供一种具有高发光效率和低驱动电压的有机发光元件。在权利要求1中表示的稠环化合物中,其一般式[1]中,R1、R2和R5分别独立地选自氢原子、具有1至4个碳原子的烷基基团、芳基团和杂环基团。R3和R4各代表具有1至4个碳原子的烷基基团。芳基团和杂环基团各可能具有烷基基团、芳基烷基基团、芳基团、杂环基团、氨基和烷氧基等取代基中的至少一个。
