Abstract
Using a compound that contains a structure where a carbazol-9-yl group substituted with a perfluoroalkyl group at the 2-position and the 7-position and a structural unit having a positive Hammett constant σ(but excluding an aromatic hydrocarbon group) bond to each other directly or via a π-conjugated linking group, wherein at least a part of the carbazol-9-yl group and at least a part of the structural unit having a positive Hammett constant σand, if any, the π-conjugated linking group form a π-electron conjugated system, an organic light emitting device having a high emission efficiency can be provided.
