ABSTRACT:
A new condensed polycyclic compound represented by general formula [I]:wherein R1is hydrogen, halogen, cyano, a substituted amino or a group selected from the group consisting of alkyl, aralkyl, aryl, heterocyclic, each having no substituent or a substituent; and Ar1to Ar5are the same or different and are each independently a condensed polycyclic aromatic group or a condensed polycyclic heterocyclic group, each having no substituent or a substituent is used for an organic light-emitting device that is extremely efficient in a light output with high luminance and is extremely durable.
