Document Type and Number:
WIPO Patent Application WO/2014/065391
Kind Code:
A1
Abstract:
The invention addresses the problem of providing a benzofluorene compound exhibiting excellent performance when used, e.g., in an organic electroluminescent element. A luminescent element having an exceptional element service life can be provided using, e.g., a benzofluorene compound having two "amino groups substituted by an Ar group and dibenzofuranyl group (or dibenzothiophenyl group or carbazolyl group)" bonded to a benzofluorene backbone represented by general formula (1) as a material for a luminescent layer of an organic electroluminescent element (in the formula, R is an optionally substituted alkyl, etc.; Ar is an optionally substituted aryl, etc.; A is O, S, or R2-coupled N; R2 is a hydrogen, alkyl, etc.; and at least one hydrogen may be substituted by deuterium in a compound represented by formula (1)).
